Wow gold players do not have that concern at this time.
Two Mutilates and a Cold Blood Eviscerate within one Kidney Shot duration is a ton of damage, and is possible with unglyphed Vigor and no Overkill. Add a partner or an interrupt or whatever and it can mean death for most players in very few GCD.Overkill and glyphed Vigor are something we will probably look at for 3.1, depending on how the current changes shake out.Rogue poison damage had at least two bugs in the system when Lich King launched. When we fixed those bugs, rogue damage dropped significantly.There is speculation that the same thing is true of Dirty Deeds -- that because Dirty Deeds was inflating poison damage more than we realized that rogue damage will drop too much with the Mutilate changes and Dirty Deeds bug fix.Wow gold players do not have that concern at this time. We are happy with Mutilate's extra damage to poisoned targets to be 20% with or without Dirty Deeds. We plan to increase rogue PvE damage in other, such as through the announced (but not finalized) Hunger for Blood, Killing Spree and Lightning Reflexes changes in 3.1.Whether the Mutilate change and Dirty Deeds hotfix will be the death knell for rogues in PvP, we will continue to pay attention on it.Voidwalker won't continue to be an excellent tank for challenging raid content.The health boost was largely for PvP reasons and the damage avoidance was to make up for limitations in pet AI and master control, not to let you opt out of having to manage tons of incoming damage on your main tank.
