Aiming with a controller needs to be revamped. It's very choppy, and lacks the sensitivity to make precise movements with the right stick. I'm always over correcting and shooting to the sides of my target. With the new deadzone settings, if you turn it up high enough and rotate the thumb stick, the reticle will make a square on the screen, which I believe is evidence of a lack of diagonal movement. Some kind of advanced settings to adjust the aiming response curve, more than just turning it up or down, would be a good start. I play on mouse sometimes and it's so much easier to line up a shot, and I have very little mouse experience.
