Ok... here is the problem. I am a fairly good fighter pilot. I fly largely vanilla ships. I have more than once come across gunboats wth full missile turret loadouts and it is more than unfair.
You basically dump all your counter-measure ammo in about 5 seconds then the next volley of missiles makes you explode, no matter how much you dodge.
Then when people go out and set these ships up with the expressed purpose of doing nothing but hunting xenos, who can't fly anything other than fighters or bombers... not so cool.
I think it would be fine if only the GB missiles used ammo, then we would have way more balence in game.
