I would not miss pivots at all.
I'm concerned about a few things that seem to be missing from Nova that made ships more special. I hope Nova isn't too bland and "hard scifi" only.
Pivots and armour plating have gone it seems. I struggled with the last version a little to represent special ships in B5 such as the White star and Vree ships but I got there in the end. Now it seems ships all just have variations on the same few options.
I hope I'm mistaken because I've been sooo looking forward to this new version.
