Could you please elaborate this?
I have no issue with TSM 2.X assigning _multiple_ auctioning operation to lets say a MoP Potion Group.
I think what he's saying is that there is no simple way to set tsm up properly since prices fluctuate alot on different servers and over time. If ypu want to set it up properly you need to have a good grip on how expensive your crafting is, what prices are on your server, etc, the sort of stuff that comes with experience of the market on said server. When you know stuff like that, tsm is a piece of cake to set up.
