I'd love to see some more NPC costume pieces become available, if possible. Things like Tyrant's shoulder guards or the D.U.S.T. Camo suits from first ward. I know a lot of NPC costumes are one piece but any that can be made available would be awesome.
Also gotta throw another hat in the ring for more content. Wharf filled in would be nice but I'd really like to see more signature arcs. Maybe some that follow some of the smaller NPCs.
P.S. - I'd also love to see the Romulus/Romulus Nictus swords added to dual blades. Love the look but not on broadsword.
