With how lethal the AI is, leaning is very handy to improve survivability in close combat.

However,

The lean option feels bad/broken in reforger.
If you compare it to ArmA 3, the double tap E or Q on pc never seems to work for me.. I always have to at least tap fast 6times in a row to get it active to begin with.
It needs tweaking.

Adding an option in your setting like aiming to set the lean to toggle would be a helpful start to make leaning usefull again in reforger.

Please consider adding this.

The lean is also very slow for some reason, on console it's a real pain.
