Bla a missile fighter is only usefull when server is low. Over 100 players and missiles are just dumb fires. Even torps get useless. Watched 3 bombers spamming torps at a GB earlier when count was 160. They were going everywhere but towards the GB.
The ammo cap used to be at 50 years ago. At some point, it got raised to 70. I'm pretty sure it was just a "Hey, let's give ourselves a few more missiles in our ships just for the hell of it" thing. So 20 more, why not? I don't think the numbers were ever really discussed back when the cap was raised. It was more than 50, so that was good enough.
