AST is very capable of doing A1S. I healed through Faust w/ it. Couldn't get further b/c AST dps is too low though, lol. I had to switch back to SCH.

Also, Celestial Opposition works on Lightspeed. I have less MP problems playing the class after the buffs.

The class is still inferior to WHM/SCH, and Selene is better at buffing than the supposed buff class.
