As a previous main WHM, I can say firmly that AST is my new main, without question. It's a gorgeous class, and there are lots of little things that can be done with AST that you just can't do with other jobs. The emergency healing potential with three instacast spells (if your benefic II gets a combo) can take a tank from next to nothing to full and shielded or regened with next to no delay.
The only thing I could ask for that would make our job easily acceptable to those who are unwilling to see it as anything outside of whm or sch jr. would be sect dancing. Granted, we don't NEED it, we're amazing as it is, but that's not the point, no one sees ast as anything other than a poor replacement instead of looking at it as something new. Don't forget that people hated on scholar as just a glorified dps with some healing abilities. It took a while for people to learn the ins and outs of the job and they came to love it. AST time will come, buffs or no, we're already relevent, hang in there my fellow AST's!
