I think it depends on the type of mission or play style you have, if you’re more of the “hack and slash” type of player you should play Berenica or Lisbell, they have consonant weapons that with the right wedges and weapons deal a decent amount of dmg by just spamming the attack.

If you’re more of a chilling playstyle (infinite type of missions, ez clear rounds of enemies) you should play rebecca or Lynn, they depend a lot on skill dmg and so.
Rn idk if there are any decent teams.
