Astro underwhelming in endgame?

[Muahbec]

On the healing department AST is really good now.(Almost good enough to replace WHM, again ALMOST, don't get me wrong)
On the CARD department though...ugh.....
Buffs don't provide THAT significant help( you can easily live and beat stuff without them... so what's the point of them anyway) the card related skills( Shuffle, royal road, spread, draw) are kinda of messy and the cooldowns could be reduced to make AST more of a buffer (after all that's what they were supposed to be right?) ALSO the RNG is beyond disappointing.
