Actually, I am level 41 and up to this point, I have only had to team up twice (one for each of the two previous dungeons I had to do), so I am not sure how reflective that statement is of actual game-play. That may deem true at end-game or for getting all the possible gear you can get, but as far as the story goes, soloing over half the levels so far has deemed that not always true. (At least for the main questline and the job/class questlines I have done so far, not reflective of higher levels or content I haven't came across yet). I think for as much as I have solo'd it, I am satisfied with the content I have gained access to. Once I hit max level, and can invest more time into focusing on the player and not the storyline, I'm sure my wanting to group up will change.
