I don't mean to be that person but people can hardly deal with the "complexities" of current AST. . I find it very doubtful that the majority of the community (well.. atleast the forums) would enjoy something like that. I think AST has a good amount of preemptive skills. Knowing when to place Earthly Star so it pops at the right moment. Knowing the right down time to pop your horoscope and such.

I like the idea of a new healer but with the three we have right now I just seems really hard to introduce a new one that has its own identity. Not to mention balance.
