The vanilla sit still, fire everyone in one go, then sit there, was quite boring and predictable.
I once modded the Borg cube ship class to a strike cruiser, where it would then spin and fire continuously throughout the combat turn.
Made for a very fun and engaging fight! As well as give more of a chance for ships to retreat.
However, it would crash upon completion of combat...

Anyone had success in spicing up Borg cube combat?
