Because they weren't essential to the game and every month the game is being developed without sales and subscriptions costs millions. 6 months later without a release would have meant cancel or studio bankruptcy, just not economically feasable. Not MMO can launch feature complete. Heck with modern graphics no MMO is rivaling the functionality of EQ2, SWG or Vanguard. EQ2 probably the only MMO ever to have interesting and engaging crafting, and Vanguard the only one to have politics, and SWG the only one ever to have classes(though it was technically class less) that was completely combat less, like dancer and musicians.
