I recently switched to KBM from controller after 15 years and I’m having rouble re-centring the mouse after a flick or 360 (I have a huge mousepad ) my arm ends up on the edge of the table and my aim gets effed how do I fix this, I play marvel rivals which is a third person shooter which requires a lot of flicks , also any tips for mastering keyboard mechanics or movement I think this is the only area a controller is genuinely better
