I get the impression that the gate isn't something you just fly through. Otherwise, why do they have so many ships on the OTHER side? If my gate was under attack by enemy fighters, I would fly through a thousand fighters rather than the Tiamat.
And yes, it would be fun to fly through the wormhole and see what's on the other side (assuming the WC gate 'physics' allowed that), however it could be difficult to do with the game engine, i.e. keeping track of TWO very large battles at once, switching between them, allowing other ships to travel backwards and forwards (an enemy isn't going to get off your tail just 'cos you flew through the gate) etc.
