Warcraft is too big and my relationship is too complicated to properly put into a concise review, but let me say this as a Retail hater for nearly 8 years:

This is the best Retail expansion in a post-Wrath world IMO. Best gameplay, best progression, and best end-game the game has been in a long, long, long time. Story and lore are very Warcraft without the edgelord shite we've had for a few years, and it's the healthiest the game has felt in a long, long time. This is hands down my favorite expansion outside of the Classic era.
