MoP was the first expanion where half the new zones were souless theme parks. Every Wrath zone was memorable.

VFW was one giant memefest, Townlong, Vale and Dread Wastes were entirely forgettable rep grind slop that did not feel at all alive.There was nothing there beyond the linear quest objectives and dailies. Jade forest and Kunlai were the only decent zones. Krasarang was a bunch of preachy bullshit about being tolerant and one of the ground zero zones for world of peacecraft. The only thing cool about it was the fighting along the beaches.

Timeless Isle is only remembered well because it first introduced welfare gear for alts and allowed pkers to coin farm their own faction.
Only The Isle of Thunder was properly memorable among the addon zones.

The Only good zones in MoP were the zones where the alliance and horde were deeply involved and entangled. This is because Pandaria itself is dull and cheesy and forgettable. Its only worked at all as a backdrop for the larger war and absent that larger war it would have been a trashcan expansion.
