I know no one wants to hear this but ive found lumi VERY helpful as a swap in on vengeance team (at least 1 front liner being on the correct forces) for 3 extra turns of vengeance passive damage when your team is about to get killed
No and save for next month (unlike most gacha games that go character by character, this game introduces "groups" (forces) of characters each month with the first banner always having the "leader" (protector) so if the protector and first unit of the new group is not where you want it then its a dead month in terms of the new group
