Assessing the Performance of Your Discipline Priest


Recently I've been concerned about my own performance. So much so that I have begun to wonder if my aging fingers and brain are simlpy not up to the demands of HC raiding in Mists of Pandaria. The reason is that I have been getting my backside handed to me by a rookie druid healer who has slightly worse gear than myself. All the podcasts I listen too that mention healing by druids always say that the druid simply cannot compete with the disc priest's imba shield. My experience however, was not backing this up.

I started to do some digging around and could find no real concrete evidence to confirm or deny either belief was the right one. While this didn't please me it gave me some hope. I therefore decided to look around and find out performance enhancing threads around on various forums and blogs regarding the healing output of disc priests to see if I could apply the diagnosis to my own play.

Overall what I discovered was encouraging as it showed that while I wasn't perfect I was far from the mark and, if I'm brutally honest, told me what I should have known just by looking at my combat logs.

The list of a what a perfect combat log should contain is here:
  • Six casts of  Penance per minute either damage or healing depending on the fight;
  • Six casts of Holy Fire/Solace per minute;
  • Six casts of Prayer of Mending per minute;
  • Five PW:Shields per minute to ensure Rapture procs on cooldown;
  • Using the level 90 talent spell on cooldown (4x Divine Star, 2x Cascade or 1x Halo);
  • Three casts of Prayer of Healing, ideally used with Spirit Shell)
  • Two casts of Archangel per minute;
  • Inner Focus used at least once per minute (again used with Spirit Shell);
  • Spirit Shell used at least once per minute (to allow for effective timing);
Over a minute that means your casting 34 spells if you ONLY stick to the above list (I'm assuming you have Divine Star). In my 570ilevel healing gear, have a 1.4 second GCD which means in total I can cast a maximum of 43 spells per minute not allowing for spells like Prayer of Healing and Penance that range between 1.6 and 2.1 seconds and Penance (between  depending on Borrowed Time.

Lets assume the worst and say I never utilise Borrowed Time and not forget that Inner Focus and Spirit Shell are OFF the GCD:
  • Six Penances = 6 x 1.9 seconds = 11.4 seconds;
  • Six Holy Fires = 6 x 1.4 seconds = 8.4 seconds;
  • Six x Prayer of Mending = 6 x 1.4 seconds = 8.4 seconds;
  • Five PW: Shields = 5 x 1.4 seconds = 7.0 seconds;
  • Four x Divine Star = 4 x 1.4 seconds = 5.6 seconds;
  • Three x Prayer of Healing = 3 x 2.1 seconds = 6.3 seconds;

This means my must cast spells consume 47.1 of the available 60 seconds which means I have 12.9 seconds left of my minute which is enough for 9 Smite's or 6 Prayer of Healing's and 0.3 seconds of downtime in my imaginary minute.

Because of the number of instant casts and the fact that I use Glyph of Penance means movement will have minimal impact on the number of spells cast.

What I discovered in my spell list was too many Smite's not enough Holy Fire's, Penances, PW: Shields and possibly a bigger crime of not enough Spirit Shell. So now I know where I need to focus my attention and as long as I am getting close to the 39 spells per minute below I'll be happy that even if I am getting out healed, I'm doing the what is needed of me.
  • 9x Smite;
  • 6x Penances;
  • 6x Holy Fires:
  • 6x x Prayer of Mending;
  • 5x PW: Shields;
  • 4x Divine Star:
  • 3x Prayer of Healing;

How To: Improve Your PC's WoW Performance


Recently I have become a bit concerned with how badly my PC is running WoW so I have done a bit of researching around on how to boost this performance without spending a shed load of cash.

My PC specs are:
  • Case: Novatech Gaming Case with 3x Scythe 1900rpm120mm Fans (1x exhaust 2x intake)
  • Power Supply: Novatech 750w
  • CPU: AMD Bulldozer FX-8 Eight Core 8150 Processor
  • Heatsink: Cooler Master TX3 Evo (with 2x Scythe PWM 92mm Fans in push/pull config)
  • Motherboard    GIGABYTE GA-770T-USB3 AM3
  • Memory: Crucial Ballistix Sport 8GB (2x4GB) DDR3 PC3
  • Graphics Card: Palit GeForce GT 630 1GB GDDR3
  • HDD: SanDisk 128GB Solid State Hard Drive + Seagate Barracuda 500GB SATA HDD
  • Monitors: 1x 23" Samsung (1920x1080) and 1x 19" Dell (1440x960)
  • ADSL: 2MB connection (I'm 8km from my exchange, so best I can get until fibre comes)
Nothing amazing but also nothing really crappy and it does deliver a reasonable rendition of WoW. However, over the summer the system had been running hot, 28C at idle, 42C when running WoW and in LFR the temp would rise to 48-50C and my FPS would vary between 10 and 60 FPS in LFR depending on activity. In normal 10 man raids I vary between 45 and 60 FPS. My graphics settings were custom running through the list my settings were:
  • Display Mode: Windowed
  • Resolution: 1920x1080 (Wide)
  • Multisampling: 8x
  • Vertical Sync: Disabled
  • Texture Resolution: High
  • Texture Filtering: 8x Anisotropic
  • Projected Textures: Enabled
  • View Distance: Ultra
  • Environmental Detail: Ultra
  • Ground Cluter: High
  • Shadow Quality: High
  • Liquid Detail: High
  • Sunshafts: High
  • Particle Density: High
  • SSAO: Disabled
  • Triple Buffering: Disabled
  • Reduce Input Lag: Disabled
  • Hardware Cursor: Enabled
  • Graphics API: DirectX 11
  • Max Foreground FPS: 60
  • Max Background FPS: 8
The biggest concern was that I was cooking my unclocked CPU and that this was killing my FPS as I knew from previous research that the main cause of performance loss while playing WoW is the CPU battering that WoW does.As my ADSL runs at a pitiful 2MB, I had already installed the Leatrix Latency Fix to ensure that I was getting the lowest latency possible. This is a registry hack, which according to the author "will reduce your online gaming latency significantly by increasing the frequency of TCP acknowledgements sent to the game server. For the technically minded, this is a program which will modify TCPAckFrequency."

Then while listening to the Bitter and Salty podcast (yes it is a WoW podcast!) they were discussing a similar issue and provided a link in their show notes to a pair of fixes (fix 1 and fix 2) they found on the official forums. They made interesting reading and made some suggestions about moving a few in game tasks directly to the graphics card software. I followed the instructions and amended the setting in my NVIDIA Control Panel and the below settings in game:
  • Multisampling: 1x
  • View Distance: High
  • Environmental Detail: High
  • Ground Cluter: High
  • Shadow Quality: Fair
  • Liquid Detail: Good
  • Sunshafts: Disabled
  • Particle Density: Good
These changes make minimal graphical difference to the game but still gave me a great performance boost as I was now running between 30 and 60 FPS in LFR depending on activity. In normal 10 man raids I vary between 50 and 60 FPS. My temperatures were unchanged. So I did some reading and found that my CPU was most likely being forced to run as a 4 core processor by Windows and looking at the task manager performance module confirmed this to be the case. A quick registry tweak (shown below) fixed that but the temps still sat in the mid 40s when running WoW. 

I also discovered that my CPU was badly configured as by overclocking it I could raise the performance and lower the temperatures by dropping the voltage (all beyond me but the instructions were simple to follow). I ended up with a smoother running PC that was now running about 5C lower.  
CPU cooler with dust jacket. Not good.
Ultimately with a big enough improvement I was happy esecially as the room ambient temperature was hovering around the 20-25C most of the time. 
But two weeks after making the change my BIOS battery decided to die and I had to replace it. Upon opening my case I was presented with a nasty surprise as my CPU cooler was covered in dust, I wish I had not gone into "ERMGHERD PARNICK" mode when I saw it and cleaned it off before thinking about a photo but the one here is a good representation.
Needless to say since cleaning the cooler up (and adding a 2nd fan to suck air through the CPU cooler in addition to the one that was blowing air through the PC is a lot happier and now sits at room ambient temperature when not under load and around 28C when playing WoW.
So next on my shopping list for my PC are some heavy duty dust filters, although I am concerned that they will reduce my air flow and increase temperatures but it can't be as bad as a layer of dust! Can it?

Friendly Fire


More thoughts on the changes brought to us in 401, sorry I can't be bothered with all the dots any more, lazy? I prefer to call it efficient.

A general rule in raiding has been "move out of the fire", the "fire" has ranged from the aforementioned fire to poison, void zones and acid. It has come in many shapes, many colours and many encounters from as far back as Zul'Gurub right the way through to Icecrown Citadel. Sure there have been a few examples where the "fire" has been good to stand in, the poison from the Sons of Hakkar in Zul'Gurub, the Blue Goop (as my old guild described the Bog Giants aftermath in Serpentshrine Cavern) and the protective bubbles in Malygos

4.0.1: Initial thoughts



Well the first few hours of WoW 4x is done. The game is looking rather stable and the priest class looking rather healthy from my very limited playtime in game so far. Not that I didn't spend much time in game, just not much time playing due to complete addon meltdown, now I am used to addons breaking after game patches but this was simply chaos and I am sure I was not alone. Many of the graphics updates seen in beta have appeared early, the floor textures in Stormwind and the new water textures, along with some interesting display bugs where the reflections in the water are showing as cloned textures rather than reflections, doh! Also noteworthy is the fact that while this has happened my framerate has got better not worse so hats off to Blizzard for making the graphics engine work harder, look prettier and be easier on the hardware.

WoW on a Poor Connection.


I have been suffering a really dodgy connection from my ISP lately, my download is all of 130Kb, which is about 15% of my normal speed. But it has made me appreciate how bad your connection can be ansd how tolerant WoW actually is of this.

Sure it has meant that I am unable to raid ICC on 25 man because even with all the settings to minimum the data flow coming from the servers creates about 1000ms of lag which is just plain bad for attempting complicated fights requiring quick get out of the fire type reactions or the hard mode fights. Dalaran too is a complete nightmare, but you guys already knew that I'm sure.
