Ideas for Warwick Rework

Quick note, I haven't put any numbers or scaling in, just the idea of a reworked kit.
Passive: Scent of the Weak. WW senses Low Hp targets(no vision given, think soraka arrows), and enhances WW's abilities on "Sensed" targets.
Q - Hungering Strike -Warwick Lashes out Empowering his next AA dealing damage based on targets max HP or Flat damage whichever is higher. "Sensed" are also slowed for X seconds. Notes: Taking the Q from his live kit and puts the damage on an AA. Giving him an AA reset helps jungle clear and damage output in general.
W- Hunter's Sense/ Beast's bite -Warwick sniffs the target gaining their scent and marks them as "Sensed" for X seconds. -Warwick can't contain the beast and takes a bite out of the "Sensed" targets dealing flat damage. Notes: This allows Warwick to get the passive bonuses on a target t
E- Bloodthirsty/Bloodhunter Stance-toggle -Bloodthirsty: 2 leg stance - bonus AS, increased when facing "Sensed" target. -Blood-hunter: 4 leg stance - bonus Flat MS, increased when facing "Sensed" target. Notes: Similar to rek'sai Un/Burrow or jinx Q manaless stat changing toggle. Gives his old passive on one stance and old W on the other provided he is facing a "Sensed" target, if he isn't than he should have lesser stats.
R-Manhunter's Pounce -Warwick jumps to a target location dealing A.O.E. damage and slows enemies a small radius. "Sensed" are stunned and receive extra damage within the small radius. Notes: I felt Warwick's live ult is only good for 1v1's, solo lane ganks can catching extremely out of position carries in teamfights. I feel this ult could give him more of a role in team fights while keeping the gank at 6 potential high for him. Maybe this is too much power for his ult. Most importantly i feel the suppression on his current ult is more of a hindrance to him (outside of 1v1's) than an ultimate should be.
I feel this kit keeps the thematic feel of the blood hunter chasing down low HP fools, and retains the sustain-fighter/Drain-tank with his Q, although he does lose the healing from his live passive and ult.
Th-Th-Th-Th-That's all folks. Thanks for reading and if you like to rip my heart out go ahead and tell me how bad this is.
Jokes aside give me some critiques, I enjoy feedback of all kinds.
