i think they should nerf warwick
hes like 56% winrate now. But if that's not enough its because he can clear really, really fast and can solo drags at l4.
Basically, everything that the update changed works in his favor, because with camps spawning faster the fast clearers are now favored, and with drags being so important being able to do them really early and easily also works in his favor.
On top of that he was already an incredibly effective jungler because he has cc and a gap closer making it hard for laners to survive his ganks.
