Hoenstly I miss the simplicity of some of the older champs, I like Dr Mundo as is and honestly don’t want to see him reworked to have an over loaded kit. He doesnt reaaly need a different kit.
So Dr. Mundo main here, got to plat in the past 2 years one tricking him. Something that needs to be understood is that you have to play for the macro game, whatever happens you have to think about the consequences of what you're doing because of the fact that he's so specialized. And that's why I play him, with a relatively low skill cap in comparison I'm free to focus on objectives and the map as a whole.
