Mundo rework concept

Theme: Mundo, a tank who goes where he pleases, using massive heals and a large health pool to wade through the enemy. Though he lacks in CC, he makes up for it by being nearly impossible to kill, lock down, or... bother in any way. Mundo is a wall of burning meat, empowered by steroids and his own twisted mind to the point of feeling no pain from anything.

There will come a point when your team is incapable of killing Mundo. Your job is to end the game before he reaches that point.

Passive: Adrenaline Rush 10 second cooldown Dealing damage to/receiving damage from a champion or large monster will cause Mundo to heal for 3% his maximum health. While this is on cooldown, Dealing/receiving damage from champs or large monsters will reduce the remaining cooldown by 0.2 seconds.

If Mundo takes damage from a structure, this cannot be activated for 3 seconds (this cooldown cannot be reduced)

Q: Infected cleaver 7.5% current HP, 4 second cooldown Mundo throws a cleaver in a straight line, dealing either 80/130/180/230/280 (+.5 AD) OR 15/18/21/23/25% the targets current HP as magic damage to the first unit hit, whichever is greater, and slowing the target by 30% for 2.5 seconds.

Hitting a unit will heal Mundo for half the cost of infected cleaver, hitting a champion doubles the heal, and killing the target doubles it again.

While Infected cleaver is on cooldown, Mundo will slap his opponents instead of hitting them with a cleaver, as his weapon is disarmed (cosmetic, no gameplay change there)

W: Burning Agony 2% current HP per second, 1 second cooldown Toggle: Deal 35/50/65/80/95 (+.2 AP) (+3% Mundos max HP) magic damage every second in an area around you. While active, mundo gains 10/15/20/25/30% tenacity.

E: Masochism 25 HP, 7 second cooldown Mundo gains 30/40/50/60/70 AD for 4 seconds, increased by 1% per 1% his missing health. While Masochism is active, taking damage reduces the cooldown of Adrenaline Rush by an additional 0/0.2/0.4/0.6/0.8 seconds (total of 0.2/0.4/0.6/0.8/1.0 seconds).

R: Sadism 15% current HP, 75 second cooldown Passive: Healing reduction reduces Mundos healing by only 40/30/20% For the next 12 seconds, Mundo gains several buffs

• regenerates 40/45/50% max HP over the duration
• Other abilities have no health costs for the duration
• 12/25/35% movement speed
• Dealing damage to champions reduces the cooldown of Adrenaline rush by an additional 0.2/0.5/0.8 seconds (total of 0.4/0.7/1.0 seconds)

Buffs:

• Passive is more noticeable, burst healing makes for more exiting gameplay than persistant HP regen.
• AD ratio added to minimum damage on Q
• Q potential heal up
• Q slow duration up
• W Damage now scales with HP
• W cooldown reduced
• E health cost down
• E (masochism) rewards Mundo for getting hit by increasing the frequency of his heals
• R health costs down
• R makes ignite counter Mundo less.
• R negates his HP costs and (Sadism) rewards him for hitting things by increasing the frequency of his heals.

Nerfs:

• Passive less useful in towerdives
• Q health cost up
• Q slow intensity down
• W health cost up (% HP per second)
• E damage down
• E duration down
• R heal down
