In a quick thought jump drive should be included in the game as well as cloaks as they are both very real in today's time. The military has special paint that bends light around an object. However it may be that cloaks in the game may be a little to powerful maybe having them cause a distortion to their background would help balance the equation.
On a more pressing note I think the use of jump drives as weapons is brilliant. The only thing I would say is that even though it has a long charge time it is less desirable to not have any control on your situation. as most space games have interdictor ships. I think that at the cost of a main gun a ship cruiser on up could mount a interdiction module. This would keep any ship withing its range from performing a jump. Which in-turn would require the attacking party to eliminate the interdictor ships before attempting a jump. It also limits the number of interdictors in a fleet, and gives the fleet assets to protect. Sort of a support version of ships.
