It was really bad this patch, especially with crafted gear. I saw stuff drop to 1/100th of the original price in a matter of a couple days... and a lot of it was people undercutting by huge margins. Some of it I just didn't get, like good. Thavnairan Chai was selling for 8-9k a pop on my server for HQ and selling decently well. Next thing I know, some dude drops the price in half and it spiraled down from there.
