hate to be that guy.... but nuke build ww is by no means a new thing. Its been around ever since Feral Flare came out. How do we stop ww from being a click R to win champ... counter jungle. Watch a few pros or experienced people jungle agaisnt a ww. You will notice that they counter jungle like crazy. For example off the top of my head Trick2G has a game up on youtube where he Nunu's vs a WW.... AND DESTROYS the ww simply by practically living in ww's jungle.
If you let a farm jungle champion farm jungle then of course he is going to be a monster late game. This is not only ww, this is yi, ww, udyr,hecarim, and skarner. If you leave them in their jungle alone for 20 minutes.. Its game no matter what, because all 5 will 1v3 easily. That said if you force any of them out of their jungle and keep them out... their dead weight.
