There was about 2-3 weeks of stuff, started off with dealing with cultists, then soothing elementals, then they have elemental invasions in the world (and Outland oddly..) then invasions of the cities. Sort of ho-hum, but Blizzard's world events largely suck all the time so no surprise.
I have to laugh at the changes to the old quests - the NPC tells you where to go, when it's also in the quest text, and also the fact there's a Flight point EVERYWHERE. A guild mate continually whines about travel time in the 'Old' world so I guess people didn't like that ? Not sure if this is constant but an NPC sent me into a cave, then went with me - that way I don't have to go in and out repeatedly, but I suppose that's a nice change.
