Why is this stickied? Anyways, I play on 2. I rock at Swat, I can still turn fast. And I snipe alright. 2 seems to fit me.
Mine was ten, but then I bought an RPG recently, and it didn't have a high sensitivity, and you couldn't change it, so now when I play Halo, my sensitivity is 2. My Sniping is better now, but now I suck at Shotguns. So Shotty Snipes is an epic win and fail.
I use 5. I'm sure if I kicked it up a few notches then I would be able to earn those last two rankings and become a level 50. I'm a good sniper, better front liner, and I use the bumper jumper, so I always win melee and sword battles.
That's not the topic at hand so this is getting "off-topic" but I shall end this discussion by saying that you are able to jump, aim, move, shoot, throw grenade, etc, all while using bumperjumper...That's not arguable.
i happen to use the claw when i play, so.... well i think this is on-topic cause the sensitivity depends what control setup you have...
Ya i have been switching it a lot, but 3-5 is usally my most comfortable range. Lower is better for long range and higher is better for CQB but its all about where you are comfortable.
