My w6 adventurer is close to a 20hrs wait. But it's no big deal. I stay out of town for 1-2 weeks gathering money then make a huge town treasury deposit/purchase. By the time my ban/wait time is close to a week long, my town will be done building and I'll have most, if not all, of the items I could want. Then I'll probably just be re-skilling for duels and will want to be in town 100% of the time anyways.
