This is a variation of my FPS profile that makes Gears of war 5 multiplayer a bit less fiddly.
Basically ive added a deepclick at 35% on the right mouse button that does 2 extra jobs, firstly it presses the middle mouse click to use the zoom function on scopes. Secondly it taps the Q key to automatically Tag enemies that you are targeting.
I found it useful to remap the Top and Bottom thumb buttons to Melee and Active Reload respectively.
This takes care of the main controls in multiplayer. Feel free to remap the remaining keys to suit your playstyle.
Hope you find this useful, and feel free to tinker and add suggestions for improvement.
