Bazaars are a waste of time/space/server processing. I'd much prefer they just remove the limit of items you can have on the AH and adjusted the tax system.
I agree with this. The limit on the AH was stupid and (IMO) part of the reason many people had trouble earning gil. The best solution for the player and the economy would have been the ability to AH it all or at least place a 10-20 item limit. This is especially true since selling to an NPC was next to worthless for most items and many items didn't stack to more than 12 or stack at all. Something is wrong when I need to pay more RL money to have a mule sell what I have acquired.
In many situations, bazaars are a waste because your items that are not highly desired could sit there for weeks. I would love if there was the ability to search through everyone's bazaar in one shot. Something along the lines of a registry where you place the item you are selling and your price. Oh wait, that sounds like an AH lol.
Bazaars were good when you wanted to do something like camp the entrance to Ro'Meave with Silent Oils back in 2005. People are rarely that unprepared anymore. Even if you have an item you want to bazaar because you cannot NPC or AH it, you are better off shouting in WG and waiting for responses.
Make all AH's connected, make them accessible from many different locations and make the limit of items you can sell very high and there is should be no real need for Bazaars.
