I totally agree with Zack in this video;

Been playing since launch, and Shadowlands is just so disappointing and boring. These insane "systems" are just ridiculous already, they were sort of cool and fresh in Legion, and not as much in BfA, and now just aggravating to have in the game. I'd much rather have the MoP style of WoW back.
In my opinion though, the best recent expansion was easily Legion, man I loved Legion, so much fun, so fresh at the time, especially after WoD. I played Legion pretty much 6 or 7 nights a week a couple hours each time, for almost 2 years straight, loved everything about that expansion. But for some reason Shadowlands feels like a generic hollowed out empty version, boring, and tedious, and lacking all fun.
