actually, that's only because your "escorts" run around like recently decapitated chickens (WHAT AN GREAT COMPARISON!) spamming whatever on the bombers.
Call targets, focus on one target, have fighters stand close to the capital ship and attack a bomber when he's in his "gonna fire SNAC" mode.
Also, get a repair ship. What?
even 50cent has his hoes and pimps and whatever around him, and you'ld fly a capship solo and expect to live?
