that's pretty much flat out wrong, mice are more precise, period. if you cap the max turn speed it will do almost nothing to the most powerful part of it, which is the ability to move the sight 5 millimetres to the left and cap someone in the face. gross mouse controls are irrelevant, how often do you need to instantly shoot directly behind you?
I heartily disagree, sir. I played q2 and q3 for years in competitive clans, and the ability to do an instant and precise 180 and pop a rail into someone was crucial. Also zipping around looking for targets and quickly checking your six for a microsecond and then returning to looking ahead was absolutely necessary.
It is much easier to suggest solutions when you know nothing about the problem.
