Yea what they said lower your sens I play on 5 and I love it anything lower than 5 feels way to slow and alot of ppl are lowering they sens for H3 and most can`t look around as fast as me so it`s pretty helpful.Don`t listen to ppl like LegendJRG he`s like I play on 7 so I **** and I`m ausome cause I can jump over you and beat you in the back before you`ve turned around,Whatch some of his vids playing with good ppl he has trouble with his BR.I used to play on 10 sens in halo 2 and thought I was goo until I started playing with good ppl.And I needed to lower My sens but I did not want to because I wanted to be able to say that I played on high sens,But I had to lower it.
