Try this build, Warwick

So, I looked up champion win rates in Korea and to my serpise Warwick was in the top ten. Not looking up any builds, I went in to a blind pick game and played him. Get ghost dog first, then ionia boots with the Iceborn gauntlet. End it with spirit visage and you are golden. You get that 40% cool down and I did not think it would be this good on him. You will never die with all the hp you get back. The Iceborn helps you stay on champs thanks 40% CRD. Try it out and I think you will like it. Oh yeah, just use the last 2 item slots for what ever champs you are fighting.
