7-6, when warming up. 5, when playing SWAT or TS 4, when playing MLG/DT 3, if I'm doing terrible in MLG/DT
I read somewhere on Bungie.net about a guy and his friends who played on the default settings, then as a test, moved up to 10. After doing this, their matchmaking scores IMPROVED. Ever since reading that, i've been a 10, and I do have to say, i've gotten some amazing closeup No-scopes with the sniper and avoided being assassinated many times because I could turn around faster than the other guys : )
I started on 3, but when we started playing MLG I went down to 2 to improve my distance BR and sniping.
5 for me. I feel like I can't look around quick enough on anything lower and on anything higher I can't aim well.
I've been using 7 a lot, partly because I was on lone wolves and it helps with people ganging up around you, but lately I've been trying my hand at snipers and splazers so I think I'll probly turn it down
I got tired of people running around me and punching me in the back of the head, so I switched up to 10. It took a lot of getting used to, especially sniping- but then I learned to do the majority of my aiming by strafeing. Now Im punching people in the back of the head!
I use 2. I was playing Red Faction: Guerilla and the Beta for Bad Company 2 lately, both of which use a very low sensitivity by default. When I jumped into Halo using 6 I was all "Holy -blam- this is fast".
7 in regular games, 10 in grifball (which i play a lot, even outside of the dbl xp). you get those awesome sensor kills, the last minute turn around
10 here, mostly because all my friends think I am whacked for doing so. And also for the assassination opportunities it brings.
