I've had my Ophantom for about a year, and not once has there been an opportunity to get the better tech for it. I have all 4 of the original tech but none of the 5 newer tech. And I use the word "newer" loosely here.
Specifically I need: Spectral Flares, Proton Bombs, Targeting Visor X, Advanced Turbines, and Deflection Plating. It would be nice if there were chances to get some of those war paints for it too.
Since the end of the Wrongthinker era, tech in general has been less scarce and I think this is a big improvement. Older Unique tech seems to be where this has fallen down though.
Note: Wrongthinker did many great things for this game, but the scarce tech philosophy was bad from a player's perspective.
