I always turn these settings all the way down/completely off - as I know how to use my thumbsticks and I also choose what to do and when to do it with them myself, I do not need any "assistance" with it at all...
But... I would love to know what is keeping people from learning to use their controller properly... (Ironically, I suspect the answer simply is "auto aim")
And, yes! It was a really SMUG way to ask about it, but WTF (?!?!?!?!) Also, my perspective IS that it is just a (albeit, perhaps a mild) version of cheating.
