Looks like you're making solid progress. I would NOT go all-in for the black in summon as ON AVERAGE you need to spend 165 SCs just to get A black.

For individual needs:
Tanks: Gellius AW goes a LONG way to filling your tank needs, honestly you shouldn't need much more for pure tanking (and you have AW Bernice if you do)
Healers: AW Camilla, very good, Iris and Fedora both CC60 is great too. Max level Alissa if you need 4th
Ranged DPS: AW Elizabeth and Spica, plus Odette, CC70 Bashira, CC60 Cloris, CC60 Cyrus, Beatrice is OK and great on those rare instances you WANT shorter range. Maybe raise Marius in your spare time, especially if your Odette is her max cost of 38
Duelists: Clissa and Claudia are your go-to duelists, beyond that Cellia and Lyla are OK and maybe raise Imelia
Utility: AW Jerome is great for UP generation, as is Clissa, Len and Shuka are great for skill cd reduction and UP cost down/all attack up buff skill, Memento is nice if you need to stall heavy hitters (though Gellius can tank almost anything we have right now), Saki and Horace for ranged on melee spot, Waltz with skill will boost Elizabeth and Bashira dps through the roof

Can't comment: Shiho, Solano, Lynn

Summary: solid team that should clear most content with the right deployment setup. Focus on AW Claudia, Len and Shuka IMO, afterwards maybe Iris and/or Fedora, though the three I can't comment on due to not having might change that. Those who DO have them want to chime in, be my guests.
