Yet they don't, and WW does...
Even Godyr isn't running into my lane and 100-0 me before i can do anything with this item. Yi isnt, lee isn't, Diana isn't, Skarner isn't, etc.
Part of the reason why it is WW and not the item is not JUST that WW can kill you whenver he feels like it until you get 1550 EXTRA gold to deal with him. It is also that he is a sustain jungle. This means he can pick a champion smite over the rangers without losing too much on his clear. Other auto attack reliant junglers have to take that choice more seriously, and for many the Rangers is a better choice because of the sustain. Sure, you can nerf the jungle item...but its already not good for most jungles. They can't give it more sustain without really trashing the damage on it and making it shit. SO, seems like the smartest option for fixing this issue is either change the item so that it does not interact with WW's ult (the same way it does now) or change WW. He needs a rework anyway.
