Mike O'Brien is the president of ArenaNet, "A benefit we had in mind, You get a brand-new, unique mount skin every time, for a substantial discount versus an individual purchase price. I want to confirm to you that our next planned mount skin releases will focus on individual sales like the Reforged Warhound and bundles like the Spooky Mounts Pack. We will not add any skins to the currently available Adoption License, thus not pushing down the odds of acquiring any one skin in that set.
