Heli Fast Roping/Sling Load, and passenger weapon action
I love playing squad, not much I personally can think of that I'd like to change about it aside from the obvious. But riding around in the back of a logi twiddling thumbs (literally) while driving through an active combat zone is awful.
And I think if we could fast rope infantry out of the chopper it'd really spice up the game.
Also if we could sling load vehicle's that'd be pretty cool but I wouldn't mind not seeing it.
