Warwick Rework Idea

So I WAS writing a thread about a Warwick rework idea, but I fucking fat-fingered shift+backspace (pardon my French I just got super bummed that I did that). I had spent about 2 hours on it, but I figured I'd summarize what I was writing.

His new passive would heal based off of how much health the enemy currently had, and his current E would be moved to this new passive. the way how this healing works, is that as the enemy get's lower and lower, you would actually begin to heal less and less, but in the grand scheme of things, you would be healing more than the current passive gives.

His new Q would bolster the next 5 AAs speed by 100%, and cause his passive healing to heal for what would be the maximum amount against that current target for those 5 AAs.

His new W would cause him to leap at a targeted enemy, and causing him to latch onto them, and deal some damage over time, while slowing them, but Warwick can be stunned, knocked up, displaced, silenced, and charmed during that time.

His new E would let him see the footprints of nearby enemies (highlighted in red), and the footprints fade away after 15 seconds. This lets him find enemies that are hiding without needing his reveal.

His new R would actually become a passive. Here's how it works:

Blood will drop from nearby enemies, which Warwick can collect to increase his attack damage by 3, stacking up to 25/30/35 times. It unlocks at level 1 automatically without needing a skill point, and upgrades itself at level 11 and 16. Minions will drop 1 blood, monsters will drop 3 blood, and champions will drop 5 blood. Warwick will drop all stacks upon death. However at level 16, Warwick will only lose half the stacks upon death. EDIT: I forgot to mention that stacks drop regardless of whether ore not Warwick last hit the minions, monsters, and champions.

His new lore would also state that Warwick is now more of an unstable, carnivore rather than an intelligent hunter.

So what do you think of the idea of the whole concept?
