I was also going to recommend FFT (I look for any excuse to recommend tactics >_<), but
@LV20 Succubus already knows about disgaea, so probably knows about FFT.
I don't know why more srpgs don't have this design

It's so much more fun to battle with a bunch of generics, level up, switch classes/roles, and use skills/abilities that you want without being forced to based on hero class preferences. It adds a lot or reply value!
Anyway, I'd also recommend Front Mission 4. They are all hero characters and do have preferences towards certain builds, but you can still mix it up pretty good with how the skills/equipment works in the game, imo.
