Yeah I think the same thing too, though I've learned that there is a vast number of people who don't care or don't pay much attention to the lore and just rely on the overall aspects like "Ok, so there's this blind demon dude that I have to kill", "Ok, this expansion is about a giant black dragon who wants to kill everyone", "Ok this has pandas", etc.
But everyone enjoy different aspects of the game, and don't care much about other ones.
