Me and another affli in our guild experiences huge differences between out pets.
We both have nearly the same ilvl (505-504) and the same stat caps. After the first fights my mate realized, that the imp doing alot more damage than the observer, so i changed the pet, too.
Now there's the problem. His imp doing alot more dmg than mine (He is troll, i am orc). Also my pet is alot of times dead or respawned, his is alive the hole fights.
so any ideas? It's frustrating!
