Ok, no, WoW did not have events that changed the game world. All the events were preset and even if no faction did a damn thing, they would open up anyway. They first started with the opening of the AQ gates and some servers didn't even finish so they just opened anyway. The events weren't even that fun. Its was just doing the same thing over and over till Blizzard just opened whatever it was up.
I will say though, it is strange not to have a day/night cycle or weather but I'll manage.
