What MMO has ever had a story that was worthwhile in the long run? SWTOR maybe? Sadly I hear it failed in most other regards, so it mattered little.

Overall though, story cannot support a MMO. You clear it, and you're done. Story is 'pure' content, and they cannot keep up with players in creating that, nor can they set long term goals related to the story, as the story is the one thing everyone should be able to see. MMO's require certain mechanics that will always make them MMO first and RPG second.

Further, 1.0 > 1.23 'had' to be a fantastic transformation... 1.0 was a complete failure in their regard, and it had to change. However, 2.0 has been an overall success for them, so moving toward 2.2 and beyond will be much of the same, while expanding into new things here and there. Nothing drastic has to happen anymore.

You may not like the style of the game, but it's moving along just fine. Once they're done filling out what we've got, we'll see new systems emerge.
