Pally and dk make excellent farmers but at the same time druid doesnt need to come out of flight mode to farm and i think rogues can farm without agroing by using stealth [not sure if this is right]
I am getting a little tired of threads like this. Countless such threads have been made. Pages upon pages of people's suggestions are posted throughout the forums - go do some research.
But to throw in my two cents, so this post is not all flaming and whining: Paladin is superior, imho.
DKs are also a good choice, but with the removal of the Blood DPS specc, much of their survivability is gone. The Paladin survivability has been boosted massively.
Why are DK's 2nd in the poll then?
