I started this game back in Feb of this year. My first healer was WHM and I really liked it. Easy to heal, powerful, basic healer. I’ve played around with AST and SCH and both feel like WHM plus something extra. AST is probably the busiest of the 3 with the cards. The benefit of SCH is you start as an Arcanist, and so does Summoner. U can use SMN for the MSQ and SCH for the dungeons and the insta-cue.
