Eight years later, Mists of Pandaria is still the prettiest expansion by far.

The vibrant colors, the crisp designs, the rippling water, and the soaring soundtrack make this expansion age so beautifully. No Fel Green (tm) or Void Purple (tm) cluttering up the design scheme, just beautiful landscapes and architecture.​I've been doing the Mag'Har questline and it brought me to Pandaria and just... I did not appreciate it in its time.
