I've got to level 80 and been raiding heroic dungeons but I keep getting put down by the healers and tanks for not having high dps. I can't understand why, I've been focusing on intel stam and spirit then critical hit as that's what people have said but still poor. I've got most of my dps armour set and starting to work on the rings and trinkets. People are saying about my crit hit is too high something about certain stats have limits. I'm really in a bind guys, anyone able to help?

PS I've checked forums I just get lossed in them
