The game may be daunting to new players; you start a profession and you notice it has recipes from a year people that were born in can now vote; it has zones and instances that serve no purpose other than one-shot-farming and messy timewalking; it has working content like certain battlegrounds that most people hate.
I wonder if it's time to delete some of that and reset the game to a game with no expansions called 'Warcraft'-plain or/and make "timewalking" an actually neverending feature with stable balance a guild can do forever (or at least do it for a feat of strength only if new content should take priority).
