Funny I don't remember ever hearing that too much. The old gods and such were boring for some but they had been part of the game since vanilla. TBC had some flaws with Draenei and such, but overall was quite fine and followed up on where The Frozen Throne left off. Since final patch of WoTLK I've found nothing of interest in terms of lore in WoW. Now they are seemingly pulling stuff out of their asses, they dont' seem to have any kind of overall structure, they just come up with it as they go along, causing more plotholes and retcons to be made than one can keep track of.
