YES! PLEASE!
I was excited he was getting buffed. Then ... he got... more MR...???
I didn't really need MR. MR is not the reason he had a 47% win rate.
Mundo literally does not have a passive. He heals well because he builds Visage and 4 more tank items including warmog. The healing from his passive early and mid game don't make up for the cost of his abilities even if you land Qs well. Think of it like his 'mana regen'.
"Mundo heals for 1% total HP per 3 seconds" - about 12.5 per 1 second late game (3750HP). 16.5 per 1 second with Spirit Visage. It sounds like a lot but to be honest it's completely underwhelming. Early to mid game? Your regen is around 3-6 per 1 second, minus health costs. If you have Warmog, or if you're using R + Visage, your passive doesn't really add much. That's not even a passive. It really doesn't kick in until late game. Woo?
Garen's passive SHITS on Mundos. And Garen does not pay a health cost for his abilitys.
Gragas/Trundle/Zack/WW/Maokai/Nasus all heal better than Mundo
Mundo got left behind in mobility. He needs something like Poppy's W to stop players from escaping. The VGU update should have revealed how his E is pretty much a 100% spam ability. It should be reworked to be more interactive. It doesn't do anything, you just push it every time you can. And his passive needs to be reworked. Put that bullshit E MR buff onto his passive and make his E prevent dashes/blinks/leaps momentarily so it actually becomes a decision when to use it.
