The Mists-Logo-Small Mists of Pandaria Challenge Modes season will end some time before the Warlords-Logo-Small Warlords of Draenor (NYR) expansion.
Changes after season ends:
Achievements: All achievements associated with Mists of Pandaria Challenge Modes will become Feats of Strength.
Bronze: The “
Silver: The Pandaren Phoenix mounts awarded for a full set of Silver medals will become account-wide. If any character on an account has earned a full set of Silver medals, all four variants of the Pandaren Phoenix ([Crimson], [Ashen]ℜ ω ϖ , [Violet]ℜ ω ϖ , and [Emerald]ℜ ω ϖ ) will become available to all characters account-wide.
Gold: The cosmetic class sets will remain character-specific. Any character that has earned all nine Gold medals will still be able to repurchase the appropriate set, should they misplace theirs, from Official alliance mini-icon Challenger Soong or Official horde mini-icon Challenger Wuli in the Vale of Eternal Blossoms. Any characters that have earned one or more “Challenger’s Path” teleport spells by earning Gold medals in Mists Challenge Modes will retain those spells.
Realm Best Titles: There are extremely limited titles that are held by the players who hold the best clear time for a given dungeon on a given server. Since those Challenge dungeons will no longer be available in Warlords of Draenor, their respective titles are also being permanently removed. However, players with the best clear time for any challenge mode dungeon on a server will be awarded the title of “Mistwalker.” There will be new Challenge dungeons in the upcoming Warlords season, and new titles for which to contend, however.
