When I was at the fleet requisitions the other day I noticed the Luna class had a "unique" hull material which looked...well amazing in one word. Its the first material I've seen in this game which makes the ship look like a fed ship. When the Light bounced off the hull you could see all the "aztec" panel's and looked really cool.
Since yesterdays patch I checked back and the material is no longer on the model. I'm hoping that it just was not a glitch, and the devs are saving it for when Season 6 is available...cus I really want it. I wish I had taken some screenshots now.
