Whoa
Thanks for the rant bud, pretty sure you blew a fuse there.
I explained the entire concept of aiming in video games in the most concise and to-the-point format possible. But I guess if it hurts your feelings it's a rant? Just face it, you suck at aiming, and your mouse settings aren't to blame. You are wasting time watching overly brown townytical videos and worrying about the size of your mouse, none of it means anything at all. A veteran gamer with a $10 Logitech mouse will BTFO any dumbass with his +$3000 razer 500 button garbage who spent the last 10 years studying "mouse grips".
Just get comfortable with the mouse and it's settings and then just go play Call of Duty for 3 hours. That will teach you more about how to aim than 500 15 minute long youtube videos about le mlg trash. As a matter of fact that stuff will probably just complicate stuff and make you worse at aiming.
