I made a Perfect Star Emerald and after MIND NUMBINGLY clicking away for 10mins to make one. (I actually closed my eyes to rest and relied on the sound to re-click) I put it onto AH and accidentally listed it for less than a million instead of 7million and it was naturally sold within 1 second.
I blame the mind numbing gem creation process (why not also implement an auto crafting option?) and the lack of commas in the AH pricing amount and my lack of attention, but mostly blame blizzard for this.
Now I'm out by millions and this really crushed any motivation to keep playing. Sigh... anyone wanna donate 5million gold to recoup my losses?
