So the problem is I play different classes and different games. And every time I seem to find something comfortable and keep it for some time I just bump into another game where it doesn't feel that great.
Wait what? Just keep your mouse sens constant and change it ingame in different games lol.
For tf2 just pick the sense that feels least off for each class and play with it for a few weeks. Your senses all feel shit because you haven't put in the time to get good at any one of them yet.
