Why not? Because one class can’t have everything. Machinist gets the highest personal dps or should because it brings no utility. Dancer is the middle while bard should have the lowest dps of the three because it brings so much utility with songs.
Same with healers
Whm should be highest personal dps with a selection of dmg options not three for button mashing but a combo system that incorporates lilies more. So not it’s not fine as is.

AST needs more variety with cards also time dilation would be nice and making undraw useful. Also something so we don’t spam ma@lefic

SCH needs fairy overhaul make each distinct add more dots to weave that feed into fairy abilities or that activate differ abilities of scholar. Something.

Maybe they are waiting for the next expansion to make these classes complete?
