Innovative Vladimir Rework

I'm not saying Vladimir needs a rework but I have in my free time thought of a potential vladimir rework that would keep his identity but with a different playstyle. I'm open to suggestions and discussions changing abilities/values especially with the stacking values.

Passive Hemoglobin rush : Gains 5 stack of blood rush every time that Vladimir uses Transfusion on a champion and 2 stack on minions, neutral or epic monsters. Once reaching levels 6/11/16, all acquired stacked are multiplied by 2 (all further stacks are not multiplied until reaching next upgrade i.e: you have 50 stacks at lvl 5, you get get 100 lvl 6, but after using q on a champion, you won’t get 110 but 105 as the passive only applied for ACQUIRED stacks before leveling up) 100 stacks: 5% increased healing 300 stacks: each AP give and additional 1.5 HP 700 stacks: 7% magic penetration 850 stacks: healing increases to 10%, Each AP gives 1.7HP, magic penetration increased to 13%

Q Transfusion cooldown: 10/8.5/7/5.5/4 Passive blood pact: Vladimir applies a stack of weakening to himself and the targeted enemy up to max 4 stacks (lasts for 10 seconds). Each stacks increases the damage of Vladimir tot that target by 2.5% and reduces the damage of the targeted enemy by 5%. However, damage dealt to Vladimir by other sources is increased by 3% for each stacks. Active:Vladimir drains the life force of his target, dealing magic damage ( 90/125/160/195/230 (+0.6AP)) and healing himself for 15/25/35/45/55 (0.25 AP)

W Blood Pool cost: 20% max HP cooldown: 26/23/20/17/14 Vladimir sinks into a pool of blood, gaining 37.5% bonus movement speed for 1 second, becoming untargetable for 2 seconds and slowing enemies above him by 40% for 1 second. Additionally, he deals magic damage every half second to them and heals himself for 12.5% of the damage done.

E Sanguine well cooldown: 20/19/18/17/15 cost: 5% max health AOE: 200 Vladimir throws a well dealing 15/25/40/60 (+0.15% AP) per second and slowing enemies by 30% inside the well for 5 seconds. Vladimir heals for 20% the damage dealt to champions.

R Hemoplague _cooldown: 150/135/120 AOE: 175 _ Vladimir infects all enemies in the target area with a virulent plague which increases the damage they take from all sources by 12% for 5 seconds. After these 5 seconds, infected enemies take magic damage.
