They had something interesting going with the Queens emissary when I hit Rank 3 there were 6 new weapons that appeared I didn't see. Before there there were just 3. They could have done that same thing and have "Raid" quality loot appear on the table but requiring a much higher rank than 3 to achieve and cost all 200 (hard cap) marks to purchase for each item.
on a side note am I the only one pissed off at the poop colored rare ships? I've gotten so many blue quality ships all the same style as white and green quality and all brown AHHHHH!!!
