This is utter bull shit.
Sorry if im being rude, but I can't believe this got any upvotes. At rank 3, his windwall is 400 units wide. According to this site lanes are 1000 units wide. Which sounds about right, so I doubt its wrong and if it is, not by much.
That means that his windwall, at rank 3 isn't even HALF of the lane. You said its almost ALL of the lane. I think at rank 5, his windwall takes up half the lane, but it never even gets to 3/4 for sure. Unless your on TT or somehow got on Dominion, which you should have specified, your post is pointing out a problem that doesn't exist.
Making things up might make you sound right, but it doesn't make you right.
