I can assure you, nothing is undertuned there. If anything magic is just way too overtuned. You do not scale UP to that, but that scale down from there. People drop way to quickly in the first place.

Though to be fair I have barely any experience since the last 3-4 months and some infos might be outdated, but slowly working myself in again I have noticed the following thing to be just weirdly strong.

-SWA Tanks, mainly in variation of FB, Ghost, BK-combo mainly, that heavily use IP for big SWA boosts for their High scaling/defenses ignoring stuff.
-Any kind of Defensive "Fat Mage", has always been an issue, specially the Isenshi. It was fine back then to a degree because magic had a lot of reliable counters, which I feel like getting more and more removed to the point they feel unfairly unstopable (also party due the fact that Damage stat=Defensive stat, much like the physical variation only stronger.)
-Weapon Enchant Vulcano. This baby on a crit can fuck a party for up to true 400 BONUS damage a round per person (before fire res) alone, if you truly try hard. While yes the average is more around...75-100, thats still heavily overtuned. Even half of that would be good for some bonus damage.
-Seiryuu. I haven't tested much with him yet, but the evolved version seems utterly busted. Byakko seemed fine from what I could tell, but again. I barely tested this.
-Dynamic tomes scaling. They already get seeds, while they take a while to get and effectively use, which in my opinion warrants them being slightly better...60% Wil and 60% Def scaling for example feels super wrong. I think they should maxe out at 100% overall scaling, the seeds can carry the rest.

Thats once comes to mind at the moment, that are overtuned to a point where its unfun, together with me perceiving the damage numbers overall as a bit too high.
Though you guys probably have a bit more recent experiences with that, over a longer time than me in the last week.
