Problem with WoW has long been the players have problems with the game and it's systems and the developers don't care and just create more systems to fix the problems of previous systems...causing more problems.
That and the whole "borrowed power" template that gets replaced each expansion just means an endless grind without progression.
If you don't do raids or love World quests then there is nothing to do. Especially since professions are crap and the auction houses are busted because of WoW tokens.
Because why acquire ingame currency if you can buy currency ingame through company sanctioned RMT.
It's less what wasn't announced then what hasn't been done in the last 2 decades.
