Once our artists finish making the mount ready to ride, it will be added to the Mount Collection tab in Q1 2021 for every player with Shadowlands activated on their account . Polls will remain open for two weeks before we close them on September 18 at 3:00 p.m. PDT, so be sure to pick your favorite before then! Do take note that there are several polls from different regions to support our players around the world, and your region’s poll results will only reflect the votes counted in your region.
