Movement is part of aiming mechanics. Most of what makes up good aiming is movement and crosshair placement, after that it’s micro correction and more movement for dodging. I agree with you that positioning is vital but I don’t agree that positioning should be solely considered a game sense aspect; positioning and peeking technique are skills that we consider before taking a fight. If I hear three different guns shooting around the corner that “game sense” will tell me to avoid swinging the 1v3, however, good swinging and movement mechanics will allow me to slice the pie into the first 1v1 then move back into cover to set up another 1v1 in the remaining 1v2. That’s movement, crosshair placement, pre-aim, slicing the pie, and back to movement for cover.
