There's still some confusion with fighter colours, as most of them have been bumped by one "rarity" level, while others remained in their old form for some reason. Their capabilities and variants are the same though (i.e. there are standard, upgraded and pressumably ultra rare ones from starbases).
As for the Scorpion Hangar - the uncommon version is nothing special. I'm more curious about the rare and very rare (or should I say, very rare and ultra rare) variant.
