Since the toughest enemies have about 10 willpower/bodybuilding and the fact that you can have 150% cc efficiency and debuff willpower by -12 and bodybuilding by -9 (so 270% and 240% chance respectively) I'd say they are kinda easy.
You can reasonably debuff willpower by -12 and bodybuilding by -9? Okay, whatever that is it's not something my partner and I have noticed. If that's the math that happens, then CCs might be too strong, but I think then the answer might be to make the debuffs weaker.
