However, MK hasn't been seen around lately, and hasn't updated the information for patch 3.1, with its big changes to spirit and to Priest talents. Fortunately, a blogger named BobTurkey has stepped in and thoroughly reworked all the numbers, at great and interesting length. It's times like these that I really love the WoW community.
The overall discussion is in six parts, if you want to go through the gory details, but the end product is two sets of stat weightings, one for Holy priests and one for Discipline priests (the links are to LootRank lists for the corresponding weight scales). If, like me, you love Pawn, here are the Pawn tags:
( Pawn: v1: "Discipline31": Stamina=0.2, Intellect=0.7853, Spirit=0.3317, RedSocket=11.6824, CritRating=0.3564, MetaSocket=16.4913, HasteRating=0.2925, BlueSocket=9.2824, YellowSocket=12.5648, SpellPower=0.6, Mp5=1)
( Pawn: v1: "Holy31": Stamina=0.2, Intellect=0.7480, Spirit=0.6397, RedSocket=11.384, CritRating=0.3763, MetaSocket=15.708, HasteRating=0.3059, BlueSocket=11.1016, YellowSocket=11.968, SpellPower=0.6, Mp5=1)
As you can see, the numbers are based on MP5 - one point of MP5 is worth 1, while (for instance) one point of Int is calculated to be worth 0.748 points of MP5 for a Holy priest. Nice work, BobTurkey. But what's with that name?
