Regarding Mundo - rework suggestion

What does he even do right now? I feel like his kit is just garbage ever since the new jungle. He can't top lane, and he definitely can't jungle. He is basically a less useful version of Garen that goes where he pleases (Garen does this too).

• Passive (adrenaline rush) .75% of his max hp per second instead of the 1.5% per 5s. (currently its like .33% per second). Late game its about (assuming a 4k hp pool to allow for resistances to be built) 30 hp/s. Early game its about 4 hp/s. (this regen is not part of natural regeneration and therefore isn't amped by builing regen items)

And there seems to be a bug with his cleavers where they kill him if he is too low on hp to use them instead of reducing him to 1 hp like they are supposed to.

• Q (cleaver) should slow 25% but upon landing 2 cleavers the slow should stack up to 50%. Restores 75% of its cost if it hits a monster and 125% of its cost if it kills a monster. (less oppressive Mundo but if you can land the double cleaver it pays off) Landing cleaver reduces its CD by 25%. (no infinite sticking Mundo until he gets some CDR). Stacks on cleaver fall off every 1 per 3s not hit by cleaver (slow is now 1.5s from 2s). Gives him more utility if he outplays his opponent but also gives them slightly more time to outplay him while giving jungle mundo much needed sustain.

• W (Burning Agony) cost 10/15/20/25/30 -> 9/13/17/21/25 hp/s. Mundo gains 1% move speed for every 25 hp lost to burning agony until it is turned off capping at 10%. CC reduction now includes knock-ups. (yet again giving him more late game and slightly more early game while finally adding somebody to deal with heavy knock up based teams and fulfills then Mundo goes where he pleases fantasy).

• E (masochism) AAs now stun targets with 2 stacks of Q on them for 1s and remove the both Q stacks. Masochism adds 5/10/15/20/25 + 1/1.5/2/2.5/3 AP per 1% hp missing up to 60%. (gives mundo a second source of damage for late game so he can still build tank, assuming 205 AP from this its an extra 41 dmg per second on W max and slightly helps his clear early game)

• R (sadism) hp regen 40% -> 50% max hp over 12 -> 15s. Now removes grievous wounds upon casting and causes W to reduce the duration of grievous wounds by 10/20/30% (ignite will still act as normal if used after he ults, as in no dropped time on grievous due to being tied to damage, but using it before strips it of grievous on activation of ult) can now be activated while CC'd by anything.

I feel like this would redo his kit in a way that maintains his identity while giving him the late game strength as well as early game capability to make him viable again. And this would make his kit so much more cohesive with every ability feeling like it links to his kit and isn't just thrown around and could be replaced with a different one. Also allows Mundo to be more useful with less gold.

This would also introduce a tank that could quite possibly give Vayne a run for her money if he can land his cleavers because of his massive regen values would help to counteract sustained true damage.
