I can tell you right now, all SCH needs is a nerf to AST.
That may sound weird, but SCH isn't a weak job. It's only weak compared to what AST can do, which is pretty much everything you can but better.
Same with WHM. It's not weak, but compared to AST it just seems underwhelming.
As for difficulty in healing, I think we've all had to use more of our kit to heal now.
I can no longer out a buffed Regen plus asylum up and neglect the tank anymore. Sometimes I find myself spamming Cure II and Bension. That's not SCH being weak, it's them using their full kit to heal with ,as a healer should be doing.
