The latest news on patch 10.1 has revealed some new information about Mythic+ season 2, including the availability of new rotational dungeons.
Mythic Season 2 Dungeons
- Brackenhide Hollow
- Halls of Infusion
- Uldaman: Legacy of Tyr
- Freehold (Battle for Azeroth)
- The Underrot (Battle for Azeroth)
- Neltharion's Lair (Legion)
- Vortex Pinnacle (Catalysm)
Whether unfortunate or fortunate for some, there will not be a new level 10 seasonal affix in Season 2. The rationale behind this decision is that the developers believe that the rotational dungeons, which were not available during the introduction of seasonal affixes in Battle for Azeroth, provide sufficient change for players in Mythic+ dungeons.
Additionally, Blizzard is evaluating the level 7 affix and has decided to retire Thundering. At this time, there are no plans to introduce a replacement for the affix.
