Not being able to buy single items from a stack on the marketward.

But people are already doing that. Except instead of trading area, it's the guild suppliers.

Guild suppliers only give the mats up to around lvl 20, after that you start needing items from other jobs and gathering. So pretty much they hand you the first 20 and then say, "Off you go, play with the other kids" XD
