why can ww point and click and suppress.

for squishy champs, he can just point, ult, and if ur not dead ur at least at half so he gains a movement speed boost. at the least u if u are someone like vayne or something u shud be able to e him off u. i know you can if u time it right but considering how easy his ult is to land, and the range being as long as most ranged champs autos, if you are someone like orianna, maybe you should be able to ult him off of yourself or something. idk terrible example but the main point is he can just point and click and u can do nothing but sit there and wait til its over.
