I prefer faster playstyles, with my latest all being Nova focused blitzkriegs.
To say Novas are command point intensive is an understatement. Their extreme movement system on top of their fearless AI makes them suicidal, so a mixture of civilian rally point, waypoint, eliminate on exposed ships, and direct retreat is required to make efficient use of them. Likewise, they have poor PD, and need an escort which also has to be managed.
It is worth it however. I need to try my latest build in vanilla, (curse you HMI and giving Remnants broken weapons), but I'm pretty sure I can beat five full sized Ordos with them.
Even with unbalanced mods, my fleet still can kill the big threats in the initial engagement, and then encircle the enemies spawn point before they can properly reinforce. Which results in my TT Brawlers and Tempests cleaning up the random destroyers and frigates running around, while my Novas contain and pummel anything that gets deployed.
