Personally, I like the idea of reintroducing the Fire Linked trait, where if one weapon in a battery hits all of them do. It helps simulate the idea of a big gun better (instead of your big gun rolling 9 dice and going off of that, you simply roll one. If you hit, you do 9 damage x your damage trait).
My only problem with attack dice is that it makes your big guns feel less big, instead of a big spinal mount I feel like I have several mini cannons setup. Having something like Fire Linked would change that.

I agree.  My spinal mounts are usually given slw, Dx3 and either proximity or piercing with a FR arc.  I used to use catastrophic, but my rolls seemed to always be below the 3.5 average.

It's turning a game into an abstraction.  Instead of rolling for each weapon with modifiers, let's pool all the weapons and modify that.  This also applies to damage. We no longer damage individual weapons, we damage them all at once.

The next version, Starmada Cosmic Edition, will probably just be a comparison of Offensive Combat Rating vs. Defensive Combat Rating, with a Movement Rating being used for a modifier for Initiative.  As long as the math is correct it should play the same, right?
