They didn’t even needed to touch SCH or AST. It was only WHM that desperately needed a boost. On DPS side of things, SCH should’ve stayed as the mobile DoT master, AST should’ve kept all of its buffs and had time related skills mixed in, while WHM should’ve been a pure DPS type like BLM (wind, water, aero, earth skills to rotate through). And with Sage coming in, that could’ve had the fastest of DPS skills with debuffs they could place on mobs and bosses (my take anyway, but gotta wait until the skill trailer to see what SE does )
