There is zero reason not to have a 1v1 duel option in the open world. None. No kidding things won't be balanced. The player base understands this and we can police ourselves.

SE dev/GM, legit question most of us want an answer to... do you think we aren't capable of policing ourselves in terms of 1v1 balancing?

Would give us something to do while waiting for terrible Frontline ques (ruined by GC restrictions, another terrible idea by SE)... and a way to practice. Also would make pvp gear materia slots viable (God forbid they actual have a purpose...).

FYI - simply have 'auto-reject duel invites' option to click for you complainers of dueling.
