I see Valor as a bunch of dumb Chads who train shit and then send it to be slaughtered.
Mystic is the snobby normie/autist team of "calm analysts" who think they are cognitively superior in comparison to everybody else and suck each other's dicks.
Instinct is the team that pushes through all of the normies and autists around, and uses instinct / gut feeling to get around, i.e. "Shit's about to go down at McDonald's" or "There's probably a fucking Zapdos behind that bush".
