Just as an FYI, you might want to add Troll Heritage crate back to the "New Items" portion of DBG store, otherwise people probably aren't going to know that it's available/buy it...
For sure, not nearly as many are being purchased on Bristlebane. By this point, the bazaar should be a bit flooded. There's hardly any inventory to purchase and when it's out it's $2mil. The armor is decent looking enough and the port clickies are neat. I don't believe it to be a "dud" set, people want this stuff.
It's kinda crazy to think there is only 1 truly evil race left after the Troll Heritage crate: Ogres. They've completed the Dark Elves and Iksars. Gnomes, Humans, and Erudites are semi-evil but mostly counted as neutral races.
