Devs should at least do a “Reward Deep Dive” talking about how they bring the cosmetic rewards to the game, players asked for this achievement for years during several Q&As via content creators, not only frequency between achievements, the rewards…etc
8.2 brought an unique reward like the Nazjatar Crab, Why Shadolands meta achievements for 9.1 and 9.2 just had recolors? If the Crab was a step on the right direction, How the overall game is impacted by the store?..etc everything depends on the playerbase perception.
