With the new barbarian pass coming I've been thinking about the best way for barbarians to gain decent self healing that is in keeping with the role playing theme of the class. I have had two main ideas about this,
1. An ability similar to the Druid vigor spell that is activated by rage ends with rage and scales with barbarian levels.
2. An ability similar to the divine crusader ability that heals you as you get kills based either on your barbarian levels I.e 1 d6 per 3 barb levels healed on kill scaled by devotion and heal amp. Or exactly the same as the divine crusader ability by basing it on CR.
The idea behind the first one I similar to the fast healing ability in the fury of the wild Ed tree.
The idea behind number two the "fluff" if you will is that as the barbarian destroys his opponents he feeds upon their corpses, to this end wraiths oozes constructs and other in edible enemies would not proc the healing effect and dirty things like troglodytes would inflict diseases as you are consuming their flesh, additional enhancements could allow a wider "menu" and wider resistances etc.
Just some ideas to aid in the survivability of the barbarian class helping make them EE viable.
