Which archetypes have the power to heal/ressurect teammates?
There are a number of healing and ressurection type powers in the game. The primary healer power set is the Defender’s Empathy set. Controllers can select an Empathy secondary power set, which provides the same powers, though at a somewhat less powerful level. Many of the other Defender and Controller power sets contain heals of one form or another. And, the Medicine pool power set has weaker heal and ressurect powers, so a character of any archetype can play some role as a healer.
