Disable mouse cursor moving camera

I didn't see anything for in-game / hud discussion so I decided to post this here.

Ever since beta, I remapped my abilities to 1234 and used wasd to control the camera. Long time FPS player, it just feels natural. League was my first moba so I never had to unlearn any old moba habits. The thing is, in team fights it is annoying to have my screen shift when trying to follow or target someone with a skill shot just because they are near the edge of my screen. Most people I talked to think i'm crazy for playing this way but there have to be more players out there who play like this.

TLDR - Would it be hard to implement an option to disable camera movement from the cursor/mouse?
