What if Nocturnal Sect...

I always thought of something like that too, where one of sects is strength in healing, and the other strength in buffing. Honestly i just want AST to have its own unique way in healing. Though i say this, what's better than Regen and Shields?

Another type of healing could be reactive. Thus that when you got hit, you were healed by an amount. This would allow you to have a reactive barrier that functions quite differently than white mage or scholar. On lots of mobs, it would work well, against fewer mobs it would work less, but it would also give you a very distinctive flavor. Other mmo's have used this healing method and it works pretty well.
