Ok these things are the fastest creature in ark when mounted by a human. They are great for supply runs, and just generally excellent during events. Christmas event? Can easily get supply drops. Thanksgiving or Halloween events? Can easily fly around the map at light speed and find limited time dinos. They also have less damage reduction with their freeze breath on super turkeys. They are fabulous on every map, and I have found them useful getting around th eclipse of Valguero.
