The argument is pretty much one sided I see. Your way or else. But what seems to be omitted is that the MW system differs from the AH system by preventing area based overload.
MW might seem nuts but the players are actually forced to break up into other locations by telleporation, rather than huddling in one spot and congesting the traffic. FFXI was notorious for having horridly congested AH locations. Try running through Juno at any of the AH locations and you would be doing stop motion or lag city. If you were very quick you might be able to dodge the whole mess by running like mad from one end to the other and by the time the server caught up you were through the congestion, but hesitate a moment and you would get pinned in the mob.
I dont believe the TOS lets me say who... but there is another game I have played that uses a very nonstandard AH system. This system lets you buy anyplace any time. But you do have to return to your home point to collect the earnings or items. This I thought worked very well. They called it an AH... but I don't think it was really ever an AH, not like FFXI was.
Anyway, not that you care. But I have not had any trouble finding anything I have needed in the MW since they introduced the search system. That system does not suit the theory of the MW very well and is in itself more like an AH. The star over the head makes finding your target easy but looks very strange in game.
I think the MW can work but the whole theory needs a fresh rework. It's easy enough to integrate a feature that has already been done. But to make something totally new... that takes effort.
That being said, they do need to stop playing with the MW system and get serious about the rest of the game. There are so far many thing better about previous FF titles than FFXIV. Sure it's online. But its got very little to stand on.
