I've been leveling AST and SCH side by side. Every time I unlock a new dungeon I do it on one job, and then the other. And I have to say; healing on SCH is way easier than AST. As SCH it's easy to pull from boss to boss, or as far as the dungeon will let you. Just toss down a soil, excog, fey illumination, whispering dawn, let your fairy offheal, and you can even toss in AoE dmg without loosing your tank. As AST you need all your cds and Bene2 spam at half the pull size, with no chance for any gravity in between. I understand that they want us to heal more this expac, I just wish they would give AST some more spells to actually heal with. SCH has so many cooldowns to rotate through... Fey Illumination, Dissipation, Recitation. AST has Lightspeed...
I don't want this to come off as a rant that SCH is too powerful, I just want AST to be brought up to par. I really don't understand the design decision behind some of these spells. For example why is Collective Unconscious a 90sec cd when it does half as much healing as Soil (which is a 30 sec cd and doesn't need to be held). Why is Celestial Opposition a 2 minute CD when it's healing over time is even less than Whispering Dawn (which has a 1 min CD). Why is Divination a 3 min CD when Chain Stratagem is a 2 min CD...

I really hope they give AST some more spells. It feels like we lost a lot and didn't gain much to compensate.
