Rework Warwick, nerf skirmisher and devourer.
Warwick is just too reliant on his ultimate right now, so anytime you have an item that applies on hit effects, he goes from being annoying, to being the newest thing the community cries about.
Back in April, it was stated his rework was there and that all that was needed was a VU. Could you not skip the VU and begin testing his rework? Not only would this solve long term itemization issues with the werewolf, but it would also allow him to be more easily balanced. Right now, he is a lot like Ryze, a simple change turns him broken, and another makes him flat out unviable.
WW noob) especialy if it is his only damage item sence high HP builds will make him much harder to kill than he currently is with the same build.
i think they just need to make devourer grow a bit slower. like .5 or .75 magic damage per large monster, and 2 for champs(to retain the gank encuragment)
