It's great for everyone who doesn't mind what's going on around them in-game, but for those of us that do this is a problem. Increase the sensitivity cap, please! This is my one complaint, and I feel it's in dire need of being addressed. Edit: The deadzones are rather large as well.
Most professional halo gamers play on 2 - 4, it has nothing to do with not knowing what's going on around you. Lower sensitivities just allow for a more steady shot. I bring up halo because Destiny game mechanics are very similar to it.
