Aqua Shadow missions. It's pretty annoying that the game shows an upgrade pathway for the special equipment but has no way to actually get the items you need to do it. Also more blooming for 6* characters so we can work on more "endgame" lineups, 5*s aren't even worth my coins to bloom anymore, let alone any other materials. Blooming for Ivy (New Year) especially would be amazing so I could finally get the 5th member of my main team to 80. And Ardisia simply because she's the best girl. Also more CSQs for 6*s, it's pretty ridiculous to get a 6* who's weaker than everyone else simply because the devs never made a special equipment to fill up her last item slot.
