Not everyone has a luxury to own an jump-ship like Javelin, very useful ship especially for farming. Some event fleets are way too fast and hard to catch, and this is exactly where jump ship would be very useful. Also not to mention the fact jump-ships show up rarely. I wont even try to suggest to introduce Javelin or any other jump ship again, since I am ready to bet its going to be in vain.
Instead, I will try to suggest something different, that will tremendously help players who do not own a jump ship.
My solution would be to introduce the new base module, Jump-gate, module that uses most advance, state of the art technology allowing fleets of certain mass to jump anywhere in the sector from the base. However, jump is only one way and fleet has to make its own way back to the base.
Jump gate would have a mass limit, dictating how many ships can pass in one go. Each new level of jump gate would increase the maximum mass that can go through the jump gate in one go.
Also, since module like that would require tremendous amount of energy, it would require antimatter and He3 for each jump to operate. The price of a jump would be calculated based on ship mass going through, the distance from the base and the jump gate level. Higher the level of a jump gate, more energy it needs to operate therefore increase in the price of operating the module.
I really think something like this would be very useful for everyone, especially for those who do not have a jump ship. Also, since using the jump gate costs, and it has to cost aLoT, it is unlikely that people who already have a jump ship will use this module.
One more downside of such module would be huge collateral damage upon destruction, further discouraging people with jump ships to even have such module.
Like i said, this module would be mostly for low and mid lvl players, before they can afford their own jump ship.
