The mount is now visible in game and doesn't match the preview posted above.
Excessive Grind: The "New Dragonflight Expansion Meta Achievement" requires an excessive amount of grinding to complete. Players are forced to spend countless hours repeating the same tasks or missions, which can quickly become tedious and detract from the overall enjoyment of the game.Unbalanced Requirements: The achievement may have requirements that are unbalanced or unfairly difficult compared to other achievements within the expansion. This could lead to frustration among players who feel that certain tasks are disproportionately challenging or time-consuming.Encourages Burnout: Pursuing the meta achievement might encourage players to focus solely on completing tasks associated with it, neglecting other aspects of the game. This can lead to burnout as players feel pressured to constantly grind for progress rather than exploring other content or enjoying the game at their own pace.To close out this Season in this way shows the lack of content they've been preparing.
Looks to be missing the Friend of the Dragon Isles achievement, that one is required as well.
