Oh I'm extremely concerned. I said once and I'll say it a thousand times. Current SE current class design is not good.

MCH rework in 5.0. boring but functional
DRK delirium is water down WAR.
SCH is clunky
DNC is pretty bland imo
NIN is boring outside of their burst phase.

New SMN seems like all the difficulty is gone. I think the only hard part about it will be making sure to use your jewel summons in a way to optimize damage
But ultimately I feel smn will be like mch. Visually pleasing but playing it will be boring
