It would be a wise choice to bring it next month when the next expansion drops. Would be a way to get more players hyped because this is a long awaited and one of the best crates out there.
New Moon must be coming up soon because the July showcase has the Telvanni Wizard-Lord Robe for crowns. The same thing happened with the Evening Dress being sold for 800(?) crowns shortly before the Storm Atronach crates returned. Had I known I would have just waited and bought it with gems.
