It's actually somewhat baffling that people will claim SCH and AST were never OP before, just because it's undertuned right now. The reason why these changes hit AST and SCH in the first place is because they were so incredibly strong, and the reason why WHM was left alone was because it had nothing OP to rework. If that's not telling you something then I don't know what to say.

AST needs some buffs and maybe SCH as well, but please don't claim these jobs were never OP and that WHM was always a fine job when it was struggling with any kind of identity or raid spot for 4 years.
