Does Doctor Mundo Need a Rework?

In all honesty, i focus on creating reworks for older characters because they are the easiest to fix and alter in order to fit the new standard of champions for the current League roster. Dr Mundo is one of those eye sore champions that has an old kit that just doesn't seem very fun to play as or against. So, I thought he could use a little livening up.

Now, if you notice, I barely changed his Q, W and ult. I feel like they are decent abilities that just need some love in order to match the appeal of champions like Ornn. Now, his Passive and E got a HUGE change, and I feel pretty good about his passive change. Now, before you freak out, read it carefully. He doesn't get the darn resistances permanently, at least not all of them. Also, I did math to make sure the shield he gets from his E isn't completely unfair.

The concept of Mundo right now is a purely annoying tank that doesn't face very well against burst but if you can't kill him right away, you don't kill him at all. I feel like I have completely captured the idea of a frustrating tank without making him completely over-powered. Hence why I gave him the resistance boosting on his passive, the ability to increase how much his ult heals him, and the turret pushing power. He is THE annoying tank, and I feel like any rework should focus on keeping his annoyance and sustain while making it easier to burst him (the resistance sacrifice on second ult cast).

As always, please feel free to put some feedback AFTER READING THE POST AND LINK. I had someone recently read the title of the article and write a very unhelpful comment without reading any of the post.
