I recently started playing with a friend, but all my characters are higher power level than him. This makes matches very boring. Even tho it's supposed to nerf me, I still kill everything easely. I don't care about the grind, getting better items or whatever, I just want to have fun with some challenge. Is there a way to make the game more challenging when playing with lower level players (while not making low levels completely useless)? Maybe a way to boost my friends power level to mine?
