like some said depend on the spell you use but also did the tank use mitigation? what tank and so on because I once got blamed for not DPSing enough and the mentor was a DPS and I just said one thing.

if the tank would mitigate it would be easier to DPS.

but again no matter what you play for your fun and you play the way you want no one can change that no matter what people say efficient or not you play a multiplayer game for sure but so are they
