I recently started FFXIV. I have only played it a few times, and I have some friends from XI that have helped to show me the ropes. I have enjoyed exploring the new world and getting familiar with the play style and content, but I am not going to be playing it very much. What the others have said about there being nothing in between low levels and high levels is what I have experienced. There are lots of shouts for things I can't really do, but not much going on at the low levels. The game is confusing, and as mentioned above there is almost no information online in terms of walkthroughs.
I might mess around on it a little here and there, but I am really waiting to see what they do with 2.0.
Just thought I would add my perspective as a recent newbie to XIV
