I feel as if they are doing a lot more damage than the rest or their peers. It's a little early to be picking on them already, but I just fought two frost mages in an arena and... well... As a holy paladin I must say, they popped that cherry very quickly. My partner was doing some pretty good damage (arms warrior) so I can't say anything about their shield being op, which I don't think it is, but their damage is high. Maybe a compensation or to try to make things even is lower the shatter damage? 30 or 40% instead of 50%? not a lot, but at least it's better than hearing "mage op one shot me" for months to come. They didn't one shot me, more like killed me before the deep freeze wore off :P (I think 4 seconds.) We lasted three minutes. one of them got to 20k before healing back to 138k.
