I pretty much stuck to Psychotic, Pumpkin, Nut, Freya, and Shauna for most of the game. Formy is the only character I didn't really bother with for some reason, and I used Fox, Bubba, and Fynn in specific situations. I have not spent enough time with myself to figure out how I feel he'll work in the team dynamic. I sadly feel he may suffer from latecomer syndrome where he arrives so late that it's hard for the player to mix up what they feel is a fine tuned party build. We'll see, I still have a bunch of the optional bosses to deal with in the post game.
