Final Fantasy XIV should really have a matchmaking engine, I think WoW is the only MMO with one currently, but powerful ones are becoming the norm in all sorts of games from all sizes of developers.
They're very difficult to code properly, and take lots of revision, feedback and more detailed beta cycles, so I knew it wouldn't, but it's still a goofyomission for a sequel to a game that suffered maddeningly at times with LFG issues, even when you had a friend or two in tow and make your own groups like I did.
As for some of the mystery and vagueness, it's part of the charm, IMO. Vana'diel was a really great world design, very dangerous, very mysterious. Kind of like classical UO but without the ganking! It was great fun to explore. I always had such a ball doing coffers for my AF back in the day. What a rush.
Sometimes they go a bit too far and you wind up with strategy guide/FAQ fodder which is not fun in A GAME WHERE YOU CANNOT TAB OUT, but I assume that'll ultimately be better
