Some areas were also just unfinished. The stories/quest-lines just simply ended. For example Dustwallow Marsh suddenly ends, and while you do go back that for one of the first raids (Ony) it is largely disconnected from the zone itself. WoW Classic had this stuff in spades. Areas that were masterpieces (Tanaris, WPL, EPL, Human/Dwarf starting, et al) and areas (and ideas) seriously neglected or forgotten. Most of the content added in patches was fairly high quality though, they just seemingly focused their attention on that end-game instead or revamping since "most players have levelled passed that."
