How much content do other MMO's start off with? O_o I find it hard to be sure just how serious you guys are considering how little you have actually played. What kind of content do you want FFXIV to have that others have at launch, so I can understand better what you are after?
As for the "annoying cryptic updates" you're talking about - most people who are actually playing the game are enjoying it as, when they are not leveling and whatnot, the cryptic messages allow for people to speculate on what is to come and feel immersed in a changing world. The latter of these two things is being applauded around Lodestone's forums where people are delighted at the idea that the game will have a solid feed of rumours and whatnot to fuel the feeling that we are actually in a game that is in motion rather than a game that is static until the next major patch. Even the minor patches change the text that characters are saying, making things match what is said on Lodestone.
As much as I want this MMO to succeed, I'm almost starting to become convinced that this game won't go anywhere. Which is really sad for me, since I fell in love with FFXI for 8 years and have not been able to experience that feeling in any other MMO I've played.
You haven't even played past rank, what, 14 or so? You can get to 20 in a day

I don't think you can accurately judge a MMO on that short amount of playing time. Especially when it was so long ago... unless of course you've done more since then, and if that's the case, I apologise for my assumption.
