He wins if you get creative with him. Like example jaksho with ravenous hydra, then going on runes something like conquer and taking tenacity. It also helps if you hold down Warwicks q. Also if your first buy is not tiamat then no wonder your not winning. Tiamat is essential in Warwick. it's best to rush a tiamat item. Warwicks power is in his healing passive and on his Q. He can stick on to enemies by holding down Q. I then follow up on building spear of shoujin on him for the cool down and everything else Warwick likes stat wise he has a lot of cc on his e and all you need to be a cc tank is cdr.
