I'm not sure if this belongs in General Discussion or Suggestions; given that the P2W shop has virtually everything that was available on the Paragon Market, I'm going to assume it's a bug.
The various Paragon Market permanent costume transformation powers (Rikti, Malta Gunslinger, etc.) that used to be available on the Paragon Market don't appear in the P2W shop, or at least I've been unable to find them. Is this intentional or a bug? I had several builds that made use of them back in the day; it would be a shame to have them not return.
