In my experience, this is the best build on warwick. It's better than all of the more highly rated builds. The only thing to make note of, is that chilling smite is okay if you're not worried about duels or if you're facing a very kite-y team. That's common sense though. Good guide. A lot of people go pots in stead of rejuv bead but I can assure all of you that it's stronger, being able to get a fast tiamat is so strong. Warwick is also one of the few champions that can afford to skip pots on first clear, so abuse it.
