I am on AST atm and I feel it needs Essential dignity buffed because without synastry it does nothing. I had some trouble with some tanks, mostly DRK that somehow refuse to use living dead but still wall to wall. I barely have time to dps in some runs, because I have to overshield the tanks that just drop in hp. But went in again with my static tank and suddenly I could spam aoe dps with some heals here and there. Only had to use 2 benefics at some point because he ran out of cds for a few seconds. I am leveling WHM next which was what I used in Shb and am hoping it is better. AST is powerful and you can definitely heal wall to wall but it isnt like it was with WHM in a dungeon in Shb where I could basically spam holy and then tetra or benediction. I think AST, considering all the micromanaging with cards, should have stronger point blank heals. Buff ED. Do it. Now.
