I dislike many people having the mentality that they have to rush through the content and compete with others for having slightly shinier gear than the rest. The crucial thing for an MMO for me is that it provides options for you to choose your role in the world (beyond just stat bonuses on your gear).
Exhausting yourself with the endgame grind is your own fault, but it's also a design flaw with FFXIV ARR at the moment. It seems like there's very little other stuff to do with a max level character at the moment. Especially in this case my suggestion would be that people should relax and enjoy the journey a bit more instead of rushing to the endgame. I really hope there'll be other systems, content and long-term gameplay goals in the future in addition to endgame raids though. That's sort of a niche attraction even if you'd provide a fast path to max level.
