They should take off sprint and crouch. Heck, let's take off the ability to jump as well. We want regression!
Taking off sprint has nothing to do with regression. It's wanting good mechanics in the game. Granted I don't hate sprint as much as everyone else seems to (the game is definitely better off without it, but I'm not heartbroken that it's in there). The one mechanic I do NOT like at all is no flag tossing with this nav point/magnum BS they threw in there.
