Mac'Aree ain't that bad but Krokuun and Antoran Wastes are some of the worst zones in the game. I would've liked Mac'Aree a lot more if there was any content around and inside that huge temple, as of now its a couple of WQ's and an invasion point nearby. I hate how all mobs are scattered around who's purpose is just to annoy everyone trying to navigate around the place, its bad enough that the actual terraining is done so badly. Antoran Wastes doesn't even have a story going, its just going to Illidans/Alleria's hubs and then its all WQ's.
Its not the worst patch but they really made a lot of poor design choices that brings this patch down so much, which basically also applies to Legion as a whole. Makes me wonder if Blizzard will learn from their mistakes in the next expansion.
