Mumbo's really kind of disappointing. I remember when the game was coming out and how playing as Mumbo was this big deal. But all he really does is glorified switch activation.
I guess you're right. but it was actually somewhat fun to use him and have him attack the enemies with his weak-ass attack. Or even better, go into Humba's tent.
I know backtracking can annoy people. Personally, I like it much better than "enter world, complete it, get out". Feels less lazy. Besides, I like Tooie's levels more for the most part.
