Now, there's one problem with piloting a Nova. If you're gonna pilot an AI capital with Neutral Integrator, why not pilot a Radiant instead? They may fulfill different roles, but the Radiant in the hands of a player is so outright overpowered there really isn't too much the Nova has going for it, right?
If a Nova can achieve pro-rata DP of 800 (destroy ships worth 800 DP in a single battle), then it would be as DP efficient as a properly driven Radiant. I think the only ships that can hope to compare to Radiant are phase ships, unfortunately.

I like that Nova has weaker sides. In comparison, the majority of Remnant ships is either too small to generally worry about this (frigates and destroyers, though iirc most destroyers have 180 omni shields), have 270 degree shields, or are so flat it's hard to flank them. This would turn Nova into another shielded-from-all-directions Remnant ship. I suppose this can be done if Nova really needs a buff.
