Warwick rework & VU.
SKILLS
Hunter's Growth • Passive
Warwick gains 3 / 9 / 15 / 18 attack damage (at lvls 4 / 8 / 12 / 16). Upon champion kill (not assist), Warwick gains 1.5 armor.
Tormenting Jaws • Q
Warwick bites a target enemy causing it to bleed for 3 / 4 / 5 / 6 / 7 seconds and gains 5/7/9/11/13% lifesteal for the same amount of time.
Razor's Call • W
Warwick swipes ferociously, creating a blast of wind which travels in a line slowing everyone it hits by 60%. [Skill shot]
E
Need suggestions<<<
Prey Dive • R
Warwick dashes forward while howling and surpesses an enemy champion stunning them for 1 / 1.5 / 2 seconds upon hit. Warwick gains 50% attack speed after a succesful stun for 4 seconds. [Skill shot]
^Explanation: Adjustable skillshot indicator, jumps over walls. Upon dashing, you have 5 seconds to stun your target otherwise it fails. If you do succeed, you get the 50% att speed buff.
- I'd also like to suggest Metamorphosis. Much like Kha'zix's Evolve. Warwick has 1, 2 or 3 skills to 'upgrade' which make him look bulkier in game, slowly getting consumed by the beast inside him (to fit with the lore!). And an extra objective when the enemy has Soraka, like Rengar VS Kha'zix.
LOOKS

And finally, if the rework is made and we have our cool looking wolfie, I'd like to suggest his Human form skin (Lore lore lore !).
