Just to get this out of the way I play as a Scholar, so what I am about to say might sound a bit biased, but here goes.
Most of the buffs to AST are good I guess, the card buffs help mitigate RNG a bit better and they got a major boost to their potency. But I have a slight issue with the Shields. A normal AST can now create a shield that is 170% of what the initial heal is, not to mention the initial heal will be 10% stronger as well, plus the spell is instant, and has a lower cost. I feel like Scholar is losing the thing that makes it special, it's Shield. AST is dangerously close to having a doubled shield like SCH, but SCH only get it if Adlo crits, which is a bitch. I am not saying SCHs aren't still in a good place, but the whole appeal of SCH is shields. I feel like SCH needs some minor adjustment down the road, nothing big, but something, mostly with Dissipation. Think about it we have to kill out poor fairy to touch AST shields now. (Also admittedly I may just be projecting because I was really hoping for the Egi-Glamour T.T)
But the big thing I think they missed, is the ability for AST/SCH to play together both using shields, they should of made it that the stronger shield can override the other, that would be the biggest and best change in my opinion.
