The reason why the Bounty Hunter and his jet pack was removed was that it was, to put it frankly, a too tempting class. Whole teams would line up outside its secret spawn spot to have a hamsters at it, Rebels would neglect their duty and stride into the Imperial main to join the line, players would teamkill each other for it... it was reportedly a mayhem causing a lot of people a lot of grief.

Most of the developers still have the ability to spawn kits on them, though, and may do so on special occasions such as Community Games. They don't do it on request, though, so don't pester them.
