Since the new update, I haven't been able to lean to the right while using any optic that changes magnification. The controls for the controller have both the leaning to the right and changing magnification as the same controller bind. I wish I was able to change this, but there are only preset controls for the controller. Hopefully they change this and give us the ability to change the controller binds ourselves.
Controller Binds Issue
Exactly my thoughts, its almost if they don't care for controller players so they just lazily binded it with the lean right feature.
I thought they'd give us the opportunity to keybind ourselves from the day i got this game, i made better binds on the first insurgency due to steam allowing you to create your own layout. Its sad to see, but hopefully they see this.
