As a whole, I don't really mind the new marketplace, but there are some things that miff me a bit:
+ Organization by Average Buy Price: The numbers are very misleading. I'd prefer that things be organized by "Lowest Buy Price."
+ The inability to search for specific items by using quotation marks. Now if I want to find a "Jolly Hat," I have to dig through all items that have the words "Jolly" and "Hat" in them.
Likewise, there are some things that I really like/don't mind:
+ The way Game items are sold. You now see the total price, AS WELL and the price per individual items. Example:
User 1 is selling 400 tickets for 800g. It is listed 800g (total) / 2g (each).
User 2 is selling 1000 tickets for 1500g. It is listed 1500g / 1.5g
+ The 2% Listing Fee - I don't LIKE this, but I don't mind it either.
All in all, the MP is just a static thing for me. I don't consider it to be a success or a flop. I'm going to use it when I want to vend (because I absolutely hate going to the Exchange. They know good and well that the MP is severely inflated and yet most of the Exchangers STILL use it as their "price guide." It sucks. :\ ), but other than that, I could care less about it.
