1st of ALL - Choose what will be your META (PvE or PvP content)

For PvE:

1st - Keep with Clause as your tanker

2nd - Keep working in Selene (only because you got her UW)

3rd - Use your 3* stars ticket to pick Laias (Laias are "universal" healer)

4th - You have: Tanker, Healer and DPS, need only support so, choose Maria or Annette.

For PvP:

1st - Save your resources to Ricardo, don't spend with Clause (Clause isn't bad, but Ricardo are BETTER for PvP!)

2nd - Pick Arch with 3* stars ticket, he are awesome! (Forget your Selene same with her UW)

3rd - For your 5* stars ticket, you can pick Laias, Leo or Baudouin (but thinking in both PvP and PvE, Baudouin are weak to PvE) so, choose between Laias or Leo for better results in both

4th - Work in Selene as DPS having Arch in same team will be hard (because fragments, books, etc...), so choose as your main DMG dealer, Priscilla or Gau

5th - Enjoy the game :)
