1. Sev barbs should not be glass cannons no. NOR should they be self healing machines that you are trying to make them. I dont know how many here have played, or looked at the mechanics of, EVE, but in EVE there is basically 3 methods of tanking on your ships. One is the active tank where abilities refill you hp bar, in ddo that would be healing. One is the passive shield tank, this would be like the fast healing mechanic, which I am fine with for barbs so long as it doesnt get crazy. The third, which is non existant in this game and what barbs should be is the buffer tank. Buffer tanks had HUGE hp and HUGE resists, but no way to replenish them themselves (or little way), and trust me they were in NO way a glass cannon. I did a battleship in that format and stood up to 20 players shooting at me for 60 seconds with NO healing. THIS is the type of defense barbs should have, crazy high prr/mrr and dr with next to NOTHING in healing.
2. Barbs should not be getting this crazy amount of heal amp. Barbs should not HAVE more heal amp than stacked pally/monks. Further blood strength is definately broken op, and is a HUGE slap in the face to light monks. Why in the heck would a barb get more on hit heals than a light monk AND do more damage? please explain how this enhancement makes any sense whatsoever.
3. This is much less important than getting the class style correct. Barbs should be massive buffer tanks (think of this as effective hp), with very little ways to replenish it, and do Great dps. Not 70% more than every other melee like some of the crazies on here want, but 15% would be acceptable, so long as Barbs have little way to heal.
