Astrologian Speculations! How will it fit in?

but the whm already has some nice HoTs AND aoe heal c.c,,

I agree, but I'm talking about 2-3 HoTs instead of one. One that can be "released" and heal for full for emergency situations. A rolling, stacking HoT, and a casted single target light heal that adds a HoT. There's just room to wiggle, and you're right, WHM has amazing AoE's -- so if their one HoT spell doesn't step up as much as other healing spells, they'll take the AoE spot, while SCH will stick with shield stereotype, and AST becomes the HoT healer.

Just my thoughts, and I think it'll make a nice trilogy to an already great duo.

I also think there's a way to make the Esuna an interesting class type:
SCH - Removes all debuffs on one target 30 second cd
WHM - Removes one debuff from each person in party 1 min cd
AST - Removes a debuff every 5 seconds for 30 seconds, 1.5 min cd
