The whole RPG aspect of the game has blown up so badly it's pretty hilarious. The whole game is designed to people who just want to play it for the gameplay at max level, literally nothing else is even remotely well done nor do they even try. Leveling is terrible from balance to gameplay to quest design to dungeons, story spans over multiple expansion making no sense at all, even at max level you see the same characters in multiple places like Drek'Thar in your example and the writing in general is extremely inconsistent and all over the place. It doesn't even try to feel like a real world anymore, band-aids over old band-aids. I don't mind since I play single player RPGs if I want that fix but I can't even imagine how shitty WoW is to new players
