I'm not seeing much sport in applying ship cosmetics whenever someone feels like it from a game store menu though. Unless maybe you're meaning spoiling the sport of the existing game-play because you'd prefer the convenience of it?
No you see. I prefer to visit a station to change paint - as it is now - over the change we're expecting to get, I support the OP. What I'm struggling to do though is come up with another reason apart from 'a consistent universe' because there are plenty in thread who don't care about that and do want the convenience. Convenience vs consistent is 1 all, a score draw .. what's the tie breaker?
