The people that whine about Head ons are the ones who go through with the head on shot and come out with 1 wing and no stabilizers, then they run off to the forums saying they are too dumb to pull up or push down on the stick and avoid the head on shot, as for vulching, it annoys me, especially when they will avoid a fight so they can vulch someone and get themselves a second kill and get their name is lights.
Head on shots are a valid move but why try and do it, I never try and get into a head on shot but when I am I just aim and say good shot when I die or if I win i say..."hahah you and your noobfire got pwned!!!!!! i am teh 1337!!!!"
