This was the most popular spec in WoW Dragonflight season one

WoW Dragonflight season one is coming to a close, and as the game transitions to its next season, now is the perfect time to reflect on how its meta has developed through the first six months of Dragonflight. 

Particularly, the Healer meta in Mythic+ dungeons remained largely stagnant throughout Dragonflight season one (at least in terms of the classes played most prominently at the highest level). In fact, the most-played specialization across all of WoW in Dragonflight season one was a Healer: Restoration Druid.
