Eh not too sure what will change exactly. They'll be more interesting to use that's certain, i like my caps and don't see this as something that can make them more difficult to play. Seeing as how they're dumbfire, the cap pilot need only wait till they're lining up a salvo and then hammer rounds off at the bomber forcing it to break away and chances are half of what the bomber fired is likely going to miss under such circumstances. Numbers are fine in an ideal situation, i.e the total damage of 480 rockets. But in reality, you'll be lucky if half of those actually hit your target considering they can't hit anything except at close range - Lunch for anything with razors and a large amount of secondaries. Hell even people who are good at aiming Cerbs+Primes at point blank can quite easily kill a bomber making a run.
Interesting change, i'm looking forward to the ammo stack on other weapons too
