Depuis novembre 2011 officiellement, Blizzard et Valve s'opposaient sur l'utilisation de la marque DotA. Un accord entre les deux sociétés, récemment annoncé, a permis de régler le différend et stipule que Valve peut continuer d'utiliser DOTA commercialement, y compris pour DOTA 2, tandis que Blizzard préserve l'autorisation d'employer ce terme à des fins non-commerciales pour sa communauté, à savoir pour les maps Warcraft III et StarCraft II créées par les joueurs. Par conséquent, Blizzard DOTA a été rebaptisé Blizzard All-Stars.

We look forward to going into more detail on that at a later date. »
