I just completed a match where a buddy and I duked it out after defeating some AI on co-op. We just wanted to play around with some of the units in the game. I was using some Novalith Cannons on him, and he was using his Advent Deliverence Engines on me.
It seems to me that the Deliverence Engine is not very useful. He fired 5-6 shots at one of my planets and it was still 60% allegiance. Is that supposed to survive? What makes this gun worth the time consuming tech path, expensive cost and long cooldowns?
