Stats, Reforging and Gems
Strength is by far your most important stat. This is the case for Warriors and I presume Ret Pallies or anything thing that likes to smash you in the face very hard.
Gems: Always choose a Bold Inferno Ruby unless a socket provides 20 or more Strength or 40 or more of another important stat. In the latter case, use either Fierce Ember Topaz or Etched Demonseye as appropriate.
Reforging: Reforge to Hit up to the hit cap. Then, reforge to Haste, or Crit if that’s not possible. Never reforge Haste to anything else, including Hit.
The standard figures for Hit and Expertise apply. Just remembered that Hunters will need to load up on expertise for MoP. The important numbers are Hit Cap 961 and Expertise cap of 26
In order of importance stack Haste, Crit, Mastery,
With a little help from MMO Melting Pot here is the list again.
Top Priority: Diseases and Dark Transformation. Apply or reapply diseases as first priority, preferably using Outbreak, and use Dark Transformation whenever it’s available.
Second Priority: Death and Decay or Scourge Strike if Death Runes are available. Use DnD even on single-target fights. Use Scourge Strike if DnD is on cooldown.
Third Priority: Death Coil IF Sudden Doom is up or Festering Strike. Only use Festering Strike here if it will extend your diseases.
Fourth Priority: Death and Decay or Scourge Strike. This is your bread-and-butter.
From my understanding of the term Diseases this includes:
Icy Touch - Infects target with Frost Fever
Plague Strike - Infects target with Blood Plague
Pestilence - Spreads Frost Fever and Blood Plague to other targets with 10 yard radius (AOE diseases)
Outbreak - Applies Frost Fever and Blood Plague instantly
Festering Strike - Increases the duration Frost Fever and Blood Plague
Dark Transformation - turns your ghoul into a killing machine. The icon flashes when available.
Using LFR Siege of Wyrmrest - I attempted to use more diseases than previously. Reading the above I was probably overdoing the use of Pestilence. Scourge Strike and Blood Strike I used as filler attacks, and Death Coil and Death Strike as the equivalent of finishing moves. Death Strike was used for healing top ups.
I am still wearing the PVP set with 397 Bracers and Boots and achieved around 15.5K overall. I still think with some tweaks to the rotation and to the talents I can get better results especially around Blood Tap and Anti Magic Shell. After checking MAXdps I have discovered that I am not using Festering Strike, so this also needs to be worked in to the priority.
WoW lends itself to certain expectations of what is acceptable DPS and what is not, however in the process of researching this post it appears there is no definitive opinion or tool to determine what is acceptable DPS for your current gearscore. Blizzard has imposed some gating of content - 5 Man Heroics needs 329, 346 and 353, with LFR set at 372 but we don't know anything definitive about the expectations for someone who just meets the requirements.
The de facto way to gear up, is buy PvP set at 377 do the 3 new 5 man Heroics swap the cache of PvE gear for the PvP. Buy the 397 Boots and Bracers from people selling the Valor points and then enter the LFR. So somebody with a mixture of Blue PvP and 378 and 397 PvE Purples and for the sake of argument they managed to get a 378 Weapon. What average DPS should they be able to produce without the huge buffs from Well of Eternity and Madness of Deathwing?
I am guessing that somewhere in the region of 10-12K is the bare minimum for the Siege of Wrymrest and around 15K for Fall of Deathwing. These figures will rattle the troll cages, but I think they are quite reasonable. Personally I prefer to be doing 18K + before attempting Fall of Deathwing, I guess I just don't like being in position 17-19 for damage done and when the inevitable wipe comes I am public enemy number one. In my opinion lFR is more about doing the right things at the right time than smashing out the numbers, Higher DPS which comes naturally from gear just makes us all a little lazier.
Mid Term Report
Showing signs of improvement but with some areas needing extra work. I will hone my skills in the LFD, and may attempt Fall of Deathwing if I can get my numbers up sufficiently. Plan to redo the talent tree as per EJ and make more use of Blood Tap, Anti Magic Shell and Festering Strike. A few drops of the Tier set would also be nice.
