This is the latest version, with a number of little fixes here and there.
Since this is now it's own thread, I want to reiterate what I've said before, this Aldriana's Mutilate sheet, with some updates of my own to bring it up to speed. Most of the updated calculations are from his Combat sheet, merely modified to work for mutilate. Before you thank me, thank Aldriana for doing the largest portion of the work. I'm no theorycrafter, my background is in systems integration. If you think there's something wrong with my sheet, you're probably correct, please correct me.
The horde/alliance names for some things are mixed up, based on where I've gleaned information from, it's not that difficult to work out.
I've once again made an attempt at BiS, which seems to be Agi based (ArPen started to fall behind):
T9 Head, Shoulders, Chest, Gloves
Charge of the Demon Lord
Bracers of Dark Determination
Belt of the Merciless Killer
Leggings of the Broken Beast
Treads of the Icewalker
Ring of Callous Aggression
Twin Spike MH
Steel Bladebreaker OH
Gems are: one +34 (JC) Exp & one +20Exp gem to get close to the Exp cap. 2x+34Agi JC gems.
The rest are +10Agi/+10Crit in yellow sockets (to get socket bonuses), +10 to all Stats in the helm and +20Agi in everything else.
2/3MP, 1/3 TtT
Result is 9265.16dps (9635.77 with murderable target). As before, I've gotten this wrong a few times now, so if you have better by all means post.
I'd like to work on Evis with 2xIP but I'm not sure I'll get the time any time soon.
