Shadowlands set up a lot of would be great moments to greatly devestate whatever they thought they were doing with something stupid. Like Lets add Elune... THE Elune... and basiucally have her do jack all beyond force Tyrande back to being "good" and admit that she (elune) played a part in sending the elves into the maw... WOOPSIES.
Also abusing the afterlife to bring back dead characters the players might havea connection to like Varian... and Arthas... wait... yeah not them lets get DRAKA and... hmmm.. Kael! cause the 4th time was merely a setbeck (behind scenes high five)....
But really SL got a lot more shit because the game itself was getting real bad. Not *just* the lore.
