Do one of these things:
-Make his ult cost zero hp. -If you don't do that, then give him a shield when he ults for 50% of the heal and the other 50% actually heals him since everyone always has healing debuff items. -Make his e blind, no other melee champs do that and this gives him peel. Obviously increase the cd on e so he can't spam blind.
Make e longer and a blind uh, no i like taking towers with e thank you and I think they need to buff revealing he gets for killing a minion with cleaner or something, he's supposed to be the ultimate sustain, make him one
As much as I'd love to agree with you as I've been playing mundo as my go-to solution for ridiculously strong top laners, I have to say I feel like mundo is plenty strong as he stands. I honestly have no idea why he's not played more.
Mundo is very good. I don't think anything about him should get stronger
