It's your utter lack of tact and ability to see from anyone else's point of view because you have your head shoved so far up your own ass you can only smell your own stink that invalidates all your opinions.
Why not want actually new content to explore? Do you really happy with all the activities available in WoW? Do you find yourself afk in a major city most of your time? I'd argue having players afk in major cities isn't content but giving them a guild hall to show off the guilds accomplishments would be a huge draw to people.
Why wouldn't you want to have guild meet ups discussing various topics while in a great hall with nef and Onyxia's head mounted on a wall. With chairs, tables and such made by professions so once again professions matter and make gold?
If a game becomes stagnant, it dies and wow is in need of some serious innovation or it'll continue to decline.
