Procedural generation is an instanced OR single-player approach, i.e. an algorithm generates something for you in that single moment of time when your OWN game level is loading.
WoW is a MULTI-player game. So random generation doesn't work here by definition, because you and I have to share that world, i.e. it needs to look the same to both of us (and thousands/millions of other players as well), hence it can't be generated randomly.
