I'd say it was good. I enjoyed the introduction of the world quests and Suramar was cool. I liked the idea of the class hall and weapons but not sure the execution was the best. Could have done without the legendaries. I like the challenge of the mage towers. Art including tier was good, def an improvement from WOD.
Personally for me I'd say this one sits at the same level of WOTLK but def below Mists and BC. Much better than Cata and WOD.
