Great post, OP.

AST is fun, and I really like it a lot aesthetically and play style wise. I think its great to be so active as a healer.

I do agree that if they are going to buff anything it should be the effects of the tarot cards. As a "jack of all trades" class it will never have the pure healing power of a WHM or the same barriers as a SCH, but its unique asset is buffing. I would love to see the cards powered up to be a more essential part of the healing process, because I even find myself defaulting to a WHM style of spamming burst heals when things get sticky. It would be nice to have some more security in investing in card pulls, rather than treating it like a fun little extra cirricular activity when I'm not being overwhelmed "actually" healing.
