An idea for the Heavy Weapons people to give them a chance to clear the field if they need to. Because we all know all battles don't go according to plan and having all your heavy fore power under a slow effect all the time means you will lose all of you heavy weapons guys all of the time.
Adrenaline: When you need to get out; spend F, you are allowed to run with a heavy weapon, the effect lasts 1 minuet and can not be used more then once per reset. while running you can not shoot a heavy weapon.
Just an idea...
