I quite like getting several old zones with some new stuff and reputations as opposed ot just another patch island to add ot the pile, makes the world feel that much more alive to have us fighting N'zoth in areas important ot hte Old gods instead of random patch island #251 that we have no real connection to as players.
Would have loved if there was just 1 more zone, cannot think of what zone would fir the bill though sadly, i suppose Badlands.
