AST's weakness in end game

[Alisane]

The only thing that needs to be adjusted on AST is noct sect. Have CO add maybe 2% potency to already applied shields and cards...
Cards are fine. You make the most of whatever you draw.

Agree with this! The real "problem" with AST is not the class. It is that it is more difficult to just jump in and start healing with, as it doesn't have as many tools as WHM or SCH. So you have to be a halfway decent healer to do well with AST.
