Warwick is a jungler yes. He has great sustain so the new jungle doesn't really do much to him. I prefer Warwick top because then I don't have to have the constant nag of people asking for ganks before I'm level 6. With playing solo top ww you have the same free farm that you do in the jungle plus you gain more experience. This build is designed to be annoying ina ll possible ways, so taht when youw alk in the lane to save somone the enemy ahs to choose wether to give up there life for the kill or back off. The Frozen mallet rush is very usefull against champions that are good at constant harass, kinda like Riven, Jarvan, Xin Zhao, or Heimerdinger. The slow will give you that cc so you can heal from your passive properly. Youc an really just choose from a Bork or a Ravanous Hydra depending on what youwa nt to do. IF you chosoe Bork, you will see that you will sustain a lot easier in lane. If you choose to get Ravanous Hydra you will see that your cs number will be going up alot faster then normal plus its better if you ult in dureing team fights. You will want some armour by thsi time, so grab a glacial shroud or wardens mail but grab a spirit visage after, you will need it. Next you will finish up your frozen heart. next choose bettween black cleaver and wits end. Wits end for more sustain and passive magic dmg on your autos or black cleaver jsut to be a complete and utter b*tch to the enemy team. toa nswer my question why is Warwick a good top and why should you do this build? its because warwick is a great solo lane champion because of his sustain and mid game damage.
