What would happen to people with perm jetpacks? Also, maybe jetpacks have a certain usable energy of it's own and once it's out, it has to slowly refill, or you have to pay to have it refilled?
When are we gunna follow the route of TF2 and add hats and crates with keys that cost gelets... or follow CoD and make level requirements for weapons...
or even battlefield...with having to play one class, like having to work at commando for awhile before you unlike app's XD
So many idea's out there...
