Can Mundo's Q Please Get Changes?

Flat health cost that dips into irrelevancy because of the sheer amount of tank Mundo builds (and half-cost refund on a hit), current health magic damage with a minimum damage threshold, 4 second cooldown (3.6 because you never don't build Spirit Visage), and the slow is 2 seconds long on its own. Multiple times I've fought Mundos who just had to land a Q, then could essentially perma-slow me to death because once you're close enough, it's not even a matter of skill- it's a matter of spamming Q. Mundo can just perma-slow someone, get them into range of Burning Agony, and then just point-blank Q until you're dead. And because it's Mundo, you can't 1v1 him. This isn't about viability or balance, this is about fun. Being perma-slowed to death by a champion and not being able to do anything just is not fun. Especially when it's a full-tank champion like Mundo that most champions can't fight one on one.

So could Mundo's Infected Cleavers get some sort of change, please? Perhaps the slow increases with Q level, maybe it becomes slower at base but stacks? If I can't fight Mundo, I at least want to have the option of getting away. Sure Burning Agony and Sadism is a goddamn pain in the ass, but the sheer inability to get away is in my opinion way more cancerous. I'd like it if Mundo has to actually work for the perma-slow, not just land a couple of mid-range cleavers and then get a free kill by spamming point-blank Qs.

/end pathetic begging and ranting

EDIT: And yes I see I repeated myself to the point of idiotic redundancy. I'm tired and annoyed, shaddup.
