Excuse me? Not all classes have BURST self healing. Leaving BF aside, rogues, fighters and monks suffer from lacking burst self healing. The barbarian is a very odd case right now.
It is very much not the same to have CSW hitting in the 300-500 range easily without leaving combat VS having to heal with cocoon or heal scrolls.
If a class has burst self heals, then it must follow that it SHOULD NOT deal as much DPS as those who don't.
