That's not really a part of the expansion, though. It's modernizing the game because the older models and stat systems are really showing their age, but that would happen regardless, and players would experience it whether they bought the expansion or not. It just seems odd that there's nothing super enticing about this expansion to draw in players other than end game content, whereas every expansion prior had new stuff at multiple levels, and convinced players to make new characters with the new races/classes.
