Except that it's not dubious. Isn't a Hunter = can't be recruited. Backup doctor = wants to be a healer (magical or not) and will become one someday. Close to her brother = has a shortlist of who he could be (which, if Jinwoo is winsteal 3P, would be broken as more specific than a Dreamer PoE). Just because you could dream up roles with tighter justifications doesn't mean these are stupid. And yeah, it's a mismash of utility roles, were you expecting a muggle to have a game-defining limit break?
I mean when you say it like this it almost sounds not janky. Shit, is my perspective just sus-skewed on this?
