I think a really cool dynamic would be to allow them to only fire as missile volleys.

Basically, you would spam your missiles as fast as you could, but they would only launch as a volley of 2/3/4/6, dependent on your hulltype. This would alleviate the issue of missile spamming, while potentially allowing higher DPS than single launch missiles.

Love it. I have always supported multi-launch ideas. I mean missiles are cool don't get me wrong...But if someone suddenly launches a small cloud of em at you the resulting "Oh SHIT" moment is fun and exciting.
