With the exception of the Jailer not being a great antagonist and the inherent silliness of picking flowers in the afterlife, SL isn't bad by Warcraft standards. At worst you can say that it makes the afterlife too much of a video game expansion rather than a mysterious, actual afterlife but that's the nature of the beast. Its worst plotlines, that being Sylvanas and Tyrande's, are indeed directly following BFA's schizophrenic nonsense. I faceplamed as much as anyone at the SoD ending cinematic, but definitely do not share any sentiment that the lore has hit rock bottom or whatever. We've still miles to go before matching TBC, WoD and BFA. We're about Cata tier of mediocre right now I'd say.
