But it's truly a problem. At first MCH was so weak in raiding that it sometimes even got excluded in partyfinder and now they buffed it so much that MCH dominates in dps in most casual content.
If you take a look at the number in the group list (aggro list), then MCH is most of the time at the top. As a main MCH I could be happy but I am not. I would prefer a better balance.
