Yeah, I agree WotLK didn't have much of world content to offer in terms of exploration except a few rare things to camp for or so. MoP however was WoW at its prime for me. plenty of fun rare mobs to kill over and over again, lots of treasures to find. None of this was broken because of flying, on the contrary because there was no flying in WoD I coulden't be arsed to enjoy this simlar world content. However I'm very sad that you got maps spoiling where all treasures are in WoD and all rares could only be killed once and gave you all the spoils then the game was finished... :< sure tanaan brought some real rares again but then it was already too late to be enjoyable.
