It's not so much the Battleships but the Bombers that would the biggest problems. They'll have to E-K to keep up with the Battleship. It'll be beyond difficult in open space to and downright impossible in an asteroid field. Not to mention Cruise Drain. Overall, I have to admit this is a poorly thought out idea. >.>
It would be easy in open space, just hit cruise, let it wind up, and E-Kill. You'll slide by so fast there is no possible way the cap will be able to target you, especially if you are boring down his throat.
In an asteroid field the cap is going to be bouncing off far more than the bomber. Yeah, it doesn't get knocked around as badly, but it's not going to go anywhere with any speed.
With this set up the tactics will change, that's all. They won't be anymore difficult than the ones we use now.
