I would not put any hope into Living Story ever being any good, it may have improved somewhat and the devs moving towards 1 update per month instead of 1 update per second week should mean that content isnt as overly rushed out and the devs having more time to think things through (like maybe make the next large scale boss encounter instanced). Temporary content is fine to some extent, but when you focus on it as much as NeoArenaNet did, it becomes a serious problem. But unless the leadership gets heavily restructured, I don't expect things to change.
