The Auction house now pretty much lost all its use. Players now spam the heck out of it with just one piece at a time so you cannot see anything else. This is most evident with Sparks and essences. I think this needs to stop now.
The Best way to get it fixed is allow players to search through pages of the content they want to buy(if there are pages) instead of limiting the search to the "BEST" "TOP" 50 items searched.

Thank you
