As I understand it, there’s a lot of work that needs to be implemented still, not least of which being the 70+ rotations. I’m not sure what the priority is, but I can only assume that it’s a hot issue, and the miqo team is definitely working hard even around the holidays for us.
Last time I looked into this, someone had in fact made a ‘somewhat’ functional scenario for getting to the first boss and leaving, however, that was less EXP/minute than farming Sohm Al, which seems to be the only reliable, if very slow method for hands-off levelling with miqo at the moment. If you still need the links I can find them, but I don’t think a custom scenario would have what you need due to the boss AOEs being at least partially random.
