Currently, I'd like to see some kind of Gravity Well Generator (either the Star Wars version, or even maybe the Homeworld version) -- or some means of blocking hyperspace generators from working.... My last couple of games have all ended the same way --- once my opponent realizes that he is either not going to win overwhelmingly, or fears that he might lose - his ships fire off all of their seekers or fighters, and he jumps out -- he leaves the fighters with orders to do as much damage as possible, ramming if necessary..... and that's that.
We have been trying to set up a campaign, but he really prefers one off battles....
I am personally getting tired of battles where on turn one, he looks at the board - launches his fighters and seekers - then on turn 2 starts jumping before anyone else gets in range.

I do like the idea of tugs, or battle riders. One of the things I liked about B5Wars was that a good number of the escort ships didn't have Jump Drives. They needed another ship to open the gate, or they needed to use the fixed jump gates to get from hyperspace to normal space, and vice-versa. One, it will affect the tactics you chose to use and two, it gives you strategic points --- both of which would improve the game.
