The only real argument here is the time advantage. I'm fairly sure you can't bot HQ items, and really that's the only thing worth it on the market, especially as time goes on and more and more items are introduced into the economy. I'm more concerned with the fact there is no limitation to how many items can be introduced into the market than I am about bots.

Just like FF11, in the end it will boil down to rare craft item drops/+3's and the rest of the items you currently see on the market will be complete junk. It's 5 months into the game and it's already happening.
