I was thinking to be able to make 1 jump for like 200 fuel but it would take some time to calculate the jump. Like. let's say 10-20 minutes? This way we can have a carrier for eg. with 2-3 bombers jumping to a system to start a fight.
I think this is brilliant. With that sort of time frame you could remove the jump limit of 4 systems as in the that time a transport could do a trip without hanging around to long in one spot. Plus you wouldn't be able to use the jump drive to flee in a fight as it would take too long and of course carriers would be used more often which is a plus.
