So if a 850 Havoc DH takes 5 seconds to kill a mob and a 850 Holy Priest takes 8 that's a problem.

But if the health goes up the same amount for the DH when he gets to 900 as the priest that's a massive problem.

I don't understand any of this. Why should a tank or healer be able to dish out the same amount of damage world mobs as a DPS? Tanks have the ability to mitigate damage and half self heals, but as a result should deal less damage. Healers won't deal as much damage and are squishy, but they can very quickly recover that lost health. Isn't that the way an RPG based on the holy trinity should be? I can't for the life of me understand WoW has made it to this point to where every class feels they should be able to do everything other classes can. As someone who's been gaming for a long time, it's pretty well understood that DPS= high damage output, low mitigation/squishy. Tank = mitigation, high survival rate, low damage output. Healer = heals, some mitigation via buffs/hots/shields, healing, low damage output.
