Personally I have read all of the Harry Potter books, watch anime, love watching movies and tv shows. I've also read a few other books as well
But I don't care about WoW lore, it isn't even made by professional writers.
You can't compare these lores to the Lord of the Rings saga or Harry Potter, they don't feel as epic
I'm sure Blizzard has enough money to hire professional writers like Stephen King, JK Rowling or Masashi Kishimoto, until then I'm not reading any lores.
The only lore worth knowing is from WC3. Pandas were the last straw. Even then it's stupid, a game is already not real, you're reading a thing that is not real about another thing that is also not real.
