I'd like to apologize ahead of time if this is the wrong part of the forum or there's already a thread about this. I didn't find one, and this area seems appropriate, but I might just be missing something.
I'd like your formation upon entering a new area (particularly when manually resolving stronghold attacks) to be determined by your formation, not your portrait order.
I prefer to have my main character in slot 1 so they "lead" the group and I get their canned responses when I tell the group to do something, but I typically play squishy archers and mages so when I walk into an area with enemies by the entrance my main character has to spend half the fight running away from an enemy warrior or two.
