The problem is here :You can play condi burst with big sustain, u can't play power burst with big sustain.The only exeption is actually ranger, we all know the reason = pet. The big example is Thief :20 k hp with one shot condi burst.11K hp with 5k power burst. The condi weakness is also a big a problem, completely destroying power damage but not condi. You can't do actually 5K/second power damage, condi can ez. Power damage is balance, condi is not.
