Of all the champions in League of Legends, Dr. Mundo probably gets the least respect. He’s widely considered underpowered. At least a few times a week, someone on the LoL forums will call for a buff. Could he use one? Damn straight.
Does he need one? No, sir.
I’ve found him viable in Classic and pretty awesome in Dominion.
In the new game mode, a few things have shot up in priority, things that weren’t always important in Classic:
1. Speed. The ability to cap points before the other team can respond, and run away if too many of them come for you.
2. (Usually ranged) deterrence. Either to hack away at point defenders or to make attackers think again before turret diving you.
3. Small skirmish dominance. Five-on-five team fights are incredibly rare in Dominion. So you’ve got to be good in 1v1, 2v2, and, sometimes, 1v2 situations. That could mean a lot of things, so more on that later.
