Since the WoW dev staff have been dual tasked in remaking classic and pumping out new content in retail the quality of the game has suffered. The maps in the last two expansions were much larger and more detailed then shadowlands. Content wise Legion was the best expansion IMO… BFA’s ambitions were similar but fell short likely since they also had to work on remaking classic. The last patch of BFA and shadowlands seem like more of an obligation of continuing the name brand retail then making quality cutting edge content. This very well might be the last expansion and I’m not sure there will ever be a 9.2. It seems like blizzard wishes to concentrate more on remaking classic.
