Dr. Mundo really needs that VGU, hence why I always listed him as my number 1 candidate for the next slots when it got asked in these boards (alongside Rammus).
His whole kit is centered around healing. He pays with health for each of his skills. His Q refunds the health costs partially when you hit it and completely if you kill something with it, but it is a flat healing.
And he scales with health.
He is the character that gets the biggest punishment for %health damage and grevious wounds. It can completely shut him down, especially since his kit is immensely limited. He just has one skillshot with his Q. The rest of his kit is a bunch of passive effects you can activate on demand.
He needs a completely new kit, giving him new options in his fighting pattern. He just pokes you with Q til you are low enough for him to statcheck you.
The thematic of the insane serial killer, with a huge misconception in his head that a doctor is someone who is bringing people pain and that is "curing" them, has alot of potential. I would love to see it fulfilled in this game.
Unfortunately, I get the feeling that he isn't slotted for the next 2 VGUs....
It's probably Swain and another champ.... even if I think that Swains gameplay is not even close to as outdated as Mundos.... not to mention the visuals....
