Err not all boss is all about dps Ma.

U are doing correctly in those fight, far more better than someone do more damage than u but then keep on let ppl eat their volmit, create more big ooze and then lead to wipe.

Alot of fight is about holding back abit de

btw, when u say the Mage that die halfway do more dps than you, am sure you mean damage done rite? Dps is nothing, total damage done is what that matters
