Hunger for Blood now increases damage by 10% instead of 15%. We wanted to increase Assassination rogue damage, and we were succesful, but we overshot the mark. We buffed Hunger for Blood back when Assassination needed a damage boost, so we're more than happy that this talent won't account for such a huge dps increase. Because of the nature of hotfixes, it is unlikely the tooltip will change to 10% right away.

Mutilate:
- AP and Haste gear while staying above the expertise and spell hit cap and below the crit cap
- 51/18/2 spec with RS
- berserking enchants
- engineering as one of the professions if using bombs on cooldown
- Heartpierce modeling has changed based on recent findings. It appears to proc from IP procs as well as DP refreshes. With these changes Heartpierce is the best mainhand for ilvl264.
- Deathbringer's Will is a poor trinket for mutilate. It appears that Whispering Fanged Skull Heroic and Herkuml War Token are the best trinkets at level 264, but of course Abom can change that. DV heroic is still really powerful.

Combat:
- ARP and Haste gear while staying above the expertise and spell hit cap and below the hard crit cap
- 20/51/0 spec (I spent very little time ironing out the distinctions between VP and IP as well as Imp Evisc and Ruhlessness)
- berserking enchants
- engineering
- Black Bruise in it's likely implementation does not work as well as Hack and Slash
- Deathbringer's Will works reasonably well and the second trinket appears to be Whispering Fanged Skull Heroic , however Herkuml is not far behind
- trying to stay below the soft crit cap as well as the soft armor pen cap is not the best strategy. The uptime of going over those caps with DW procs is jst above 9% so it's not worth adjusting your gems for it. Basically DW is a good trinket, but some of its proc value is always wasted.

Combat is about 1600 dps below mutilate (15%) on a single target.

I am sure there will be a lot more questions for which I do not have answers yet. DW trinket has complicated analysis a lot in terms of finding optimal gear, so it will be a lot of trial and error. It is possible that AP/haste combat alternatives perform very close to ARP/haste ones. Mutilate is a lot more straightforward but seeing how close 51/13/7 is to 51/18/2, it is possible some other setups can emerge. So try it for yourself

Indeed in the simsheet, Heartpierce is below the 258 daggers in terms of dps benefit. There was a mistake in an earlier version of the simsheet where the energy benefit from HP was applied twice. After I fixed that bug and applied our best knowledge about the mechanics of Heartpierce, it came much lower. And I am pretty certain in our evaluation of how Heartpierce works by now, there were a lot of tests done to establish the proc rates and proc causes.
