No more SoG? I like it! Though if we do keep SoG as Life. I believe it needs some sort of non healing ability. Life has a ton of healing anyway. What on earth does it want more for? What if having an SoG in play meant only players with Life Marks could heal, period? Would that be OP?
Heck. You could even make it into a spell cast on a creature, giving it the ability Regenerate and some other buff.
