An idea for a Mundo Rework
So this is just an idea i had for a 
rework, criticism is appreciated just dont be an asshole please,
-Passive - Adrenaline rush - Mundo Regenerates 1% of his missing hp every second, While in combat with enemy champions this ability ramps up, up to 2-10 times based on max level (up to 10% missing HP per second) while in combat with champions for up to 3 seconds upon leaving combat (refreshes while combat)
Q - Infected Cleaver - CD 25/23.5/21/19.5/18 sec - 20% max hp cost - 1000 range Mundo throws his cleaver dealing 100/120/140/160/180 Physical damage (plus 0.4 bonus AD ratio) and slowing the target by 40% decaying 3 seconds additionally another 200/240/280/320/360 magic damage (plus 0.4 AD ratio) over 6 seconds (50% of the cost is refunded if it hits a target, 100% plus 50% of the CD if it kills the target) Additionally the cleaver remains in a target for 8 seconds, if Mundo attacks that target within that time frame he will tear his cleaver out of them, dealing 8% of his max HP as physical damage to the target and reducing the abilites CD by 10 seconds
W- Masochism - CD 40/36/32/28/24 sec - No cost Mundo stores 20/30/40/50/60% of the damage he has taken within the past 4 seconds (including self inflicted damage) as Grey Health, Upon Activation Remove any applications of grevious wounds and then Mundo will rapid regenerate the grey health over 3 seconds (every time you take damage reduce this abilites Cooldown by 2 seconds, 1 for DoT effects)
E- Sadism - CD 20/17/14/11/8 sec - 20% of max hp cost Mundo Empowers himself, causing his next 3 basic attacks to deal 3/3.5/4/4.5/5% of his Max HP as physical damage, Mundo heals for 80/90/100/110/120% of damage dealt by these attacks, Cooldown starts on the last Attack (Every time you deal damage when this ability isnt active, reduce its Cooldown by 1 second)
R - Blazing Roid Rage (joke name) - CD 130/120/100 sec - 50% of Current HP cost Mundo enrages Removing all disables and Gaining 60/80/100% movement speed and damage dealt for 7 seconds, additionally he takes 70% reduced physical damage (halved for magic damage) and Reduces Incoming CC and slow effects by 75%, During this time mundo deals magic damage to all nearby enemies equal to 5/10/15% of their Current HP as magic damage (not affected by the damage boost)
So give me your honest thoughts on this kit idea
