Eh, I wouldn't go that far.
But appreciating WoW for "mature" storylines is basically the equivalent going to a renaissance fair expecting a genuine historical experience when in fact, it's just a Walmart LARP.
Like, I love WoW and I always have. But at least I can admit it's a guilty pleasure. Stupid, childish, and testosterone-filled fun.
It's the kind of fantasy my 10 year old self would marvel at and go: "this is the deepest, most well written piece of fiction there has ever been".
And that's fine. It's OK to love dumb things. Comfort food. Escapism. Pure fun.
