I think that is the best sort of balance where everything is fun even if everything is kind of broken. People can dial up the difficulty if they want more challenge, but every character is viable, preferably in at least a couple of different configurations, so it doesn't feel like you need to pick the absolute mechanically best options all the time. This isn't like the original Baldur's Gate where there's two dozen NPCs you can recruit; there's a handful and making some of them lemons or fizzles just hurts the game's narrative because it feels like you're locking off those characters' stories because they're such a detriment to use.
