Titles and mounts have existed for the top-tier dungeons in World of Warcraft since Mists of Pandaria – where completing all challenge mode dungeons within a time frame would grant exclusive armour, title, and mounts. This concept has been worked on since then, and with seasonal Mythic dungeons being a thing, rewards are now bound to seasons, rather than expansions. This is a great feature, as Blizzard have really pushed Mythic dungeons as an endgame esport.
Shadowlands will be no different. The achievement for those who complete all dungeons in time, on a key 10 or higher, will be Shadowlands Keystone Conqueror: Season One which will grant the title, “The Sinful”. For players who manage to do the same, but on 15+ keys in time, they will achieve Shadowlands Keystone Master: Season One granting them the exclusive “Sintouched Deathwalker” mount.
This format is exactly how Battle for Azeroth is now, and we can’t see it going anywhere in the near future. Both title and theme are very fitting to the initial patch of the Shadowlands expansion, and we are looking forward to what titles and mounts Blizzard release in future seasons.
