Sprinting ability should be time-limited to 1-2 minutes

The unlimited sprinting ability makes gameplay too fast due to the little sized maps. To make it more tactical and realistic the sprinting ability should be limited for 1-2 minutes long before rest and there should be a stamina scale indicating sprinting time left.  And the  adrenaline injector which was pretty useles in Beta could give  the assault class players an ability for unlimited sprint for a minute or two. That would make it much more useful.
