I've discussed this multiple times with people. I leveled my main account playing almost sololy WW, through S5, and still play him from time to time now.
Here's my thoughts on a potential update for him:
Q: Overall, it's working as intended, although I feel the range could be a slight be extended, or give it a slow.
W: This honestly should just be his passive, or add it into his Q, so that when he hit's a target with Q, he gain's attack speed for a short duration.
E: Needs a complete rework. With as many escape mechanics as there are to escape, and he is one of only a hand full of jungler's to not have a proper gap closer, I feel that this needs to be turned into a short flash.
Here's my idea for the new ability:
Hunting Prey: Create a "Fog of War" around yourself for 6 seconds. While active, you are unseen by anyone who is not within the fog, but you are still targetable by anyone who is. You may active this ability again to leap forward, dealing 125% of attack damage on your next auto attack.
R: Honestly just needs a slight cooldown reducution, or some kind of "bleed" mechanic. I mean, you are "shredding" the emeny after all.
Anyway, I know at first look that all may seem OP, but WW is just so out of date, even for new players, that he needs somethingto spice him up desperately.
PLZ RIOT, MAKE THIS HAPPEN...........................
