Bazaar was always stupid in FFXI, It turned into another market system that wasn't searchable, so you ended up checking 100 people all sitting in the same zone. Then people who logged out couldn't log back in because too many people where in the zone AFKing. then taxes came to get people out of city and still broken.
40 spaces to sell stuff isn't enough?
I often have 40 items on market at the end of the day. Never have issue saying oo I should have sold more today.
Lastly, I would sooner they add spaces to retainers then add a bazaar system back.
