I like the new controls (LB=zoom) better than the previous ones, but there's still room for improvement. Map LB=free look, and map RS=zoom. I have mapped this already to my controller and it works flawlessly. Free look has improved drastically, as it is much less stressful to the hands and zoom is very intuitive on the right stick. Moreover, and the biggest benefit, when we are doing the 3-button-combo: sprint+free look+zoom we don't have to keep pressing a stick because of the toggle sprint! In the case of this proposal, we only need to press the LS once to toggle sprint, while as the controls are now, if we want to free look, we need to keep pressing RS (while also turning the RS to look behind). It's very stressing to the hands (and the controllers).

edit: This creates a problem in the inventory menu, as LB is no longer switch column, and we need to press RS to switch the column to the left. You can fix this by not implementing this proposal if we are in the inventory menu. eg While in inventory menu LB=switch column left.

edit 2: This also creates an interesting side effect. In order to use the optics in our weapons, as of the latest patch the order is: LT, LB and then RT to shoot. With above proposal it's LT, RS, and RT. The older "console monkeys" like myself have used RS to zoom our weapon in plenty of games.
