I'm sure the idea has been brought up before (Hell, maybe in this topic... Too tired to re-check everything), but I was just musing to myself about a "Balance" type healer that operates primarily off of HP rather than MP.

Basically, it heals itself by leeching enemy HP, and it heals others by sacrificing its own HP. Likewise, it cures status effects from others by absorbing them itself, then cures itself of them by projecting them onto enemies.

Might be considered too drastic a departure, so I don't expect many people to be on-board with it, but eh...
