We all know that in most cases jetpack is not only useless, but promotes camping and is a waste of credits. So I thought it would be a neat idea to make it like the jetpack in Firefall beta. In Firefall the jetpack is fast and you can only fly for a few seconds. When all the energy gets used up the jetpack has to slowly recharge until you can fly again.
The point is to make the jetpack a useful tool in combat rather than a useful tool for camping.
