The only thing I would change of AST

[technole]

The only thing i would do is increase thier dps by a small bit but just right below white mage and sch but to much close

Malefic II is about akin to Stone III, and it's 30 more potency than Broil. Astro DPS is just fine where it's at considering it's usually in the main healer seat.

Even for SSS trials, AST has a higher DPS completion threshold than SCH. It's WHM>AST>SCH.
