I'm not sure how far I want to roll with the Tsundere as actual mechanic, though it's definitely something I'm considering.

Spirit/Guts could be a good combination for mage-tanky schematics, possibly somewhat influenced by Pascal from Tales of Graces (whose big skills were all player-based AoE).

I also was considering a healer/support type (yes I kinda have a Valor pidgeonhole by now) who was a fangirl of a regional dark lord, with the deeper joke being that it's basically a Weird Fandom Culture, with the dark lord basically putting over-the-top supervillainous affectations on a reformist culture to make it oddly more palatable to the societies around it.
