I am guessing that in time there will be more end game content added. I don't think XI really hit its' stride with having a rich end game until a few years after NA launch. It didn't seem really good to me until there was Limbus, Salvage, et cetera all out there. They could have even made MMM end-game if they had wanted to.

What I'm hoping for is they get the game to the point they feel like they can charge for it ASAP so it's showing promise for them financially. Then take lessons learned from XI and implement some solid content for us. It should go a lot quicker for their 2nd MMO to deliver a good end game experience. They have all the lessons learned good & bad from XI. They've written the events before.

I also figure that the 1st expansion will do a lot. From what I understand Zilart was a huge addition to XI. I don't know first hand because I didn't play until NA release.
