I honestly do agree with the OP: I've bought the expansion about 2 weeks after its release and I was pretty excited to play all the way up to 60, going through the story (which I loosely followed...and I do mean loosely) and trying to do the currents while questing: I definitely take my time when it comes to expansions and even now I still take my time by wanting to replace my armor in full 170 before doing the primals and Alex normal.

Still, the game does feel like 2.0...like exactly the same and while I accepted the limitations back in 2.0, I really can't forgive this issue in an expansion. It doesn't feel like it expands properly, at least not right now.
Yes the game has decent amount of content but people should be reminded that not all of the available content is liked by everyone: I never liked the crafting in this game (even though I leveled them up to 50 eventually): is it my fault for disliking one aspect of the game? Of course not because there are others that usually should be equally lengthy.

There are those who enjoy triple triad, and those who enjoy chocobo racing..and neither of those I enjoy too, but I like treasure hunting and questing as well as exploring thanks to the flying mounts and hopefully we'll get the dailies which I used to enjoy (except the Sylphs...dear lord...the anger).

I do know we're getting more content in the next patches but I just can't thinking that it will be essentially ARR all over again with barely any true differences. I just hope I'm wrong.
