Mundo seems toxic AF
Mundo is a ridiculous scheme to play against. No matter how far back you set him pre-6, post 6 he will be an unstoppable monster and his cleavers do 295i12843598123458432185 damage through all phases, spammable and he can chase you across the map if he needs to. He runs so fast and has so many snares that you can't get away from him at a lot of points in the game.
Is a thing. and its rather cheap
with
or

For that matter any champion who does percentage damage or build a champion with the items above and you get a dead mundo.
mundo isn't involnverable he can be killed easily if you build to shred his health.
I love playing mundo, and I think he is my favorite champion, even before his rework. Having said that, I know there are alot of ways to kill him. Most people just aren't aware of how to do it.
