Here's the final word I will say on the matter before the flamers come in and ruin it 
In terms of a Final Fantasy, most definitely. The story and character development is exactly what you'd expect. Makes iconic figures that you want to see succeed and you build that emotional bond with. Also, riding chocobo's and magitek armor (way end game for magitek) is just awesome. Class structure is exactly what you'd expect and feels a lot like old school FF5 in the sense of job switching.
MMO wise, it's not anything new. It is a typical GCD, don't stand in fire, classically based MMO. Combat is simple, it is NOT innovative in that front. If you played FFXI, you'll understand that there is some grinding on your alternate classes (as you use many of the quests and main story on your first and second playthrough). There is an event system similar to GW2 Dynamic Events, and are an amazing source of exp (especially on your alternate classes as you gain 50% exp boost if your current combat class isn't as high as your highest).
Dungeons are actually really fun. I grinded some when I was leveling my healer class and, just like any other MMO, you get a mixed bag of noobs and vets.
Gathering is pretty standard.
Crafting is amazeballs, but you do need a fuckton of patience. Seriously. If you're not a crafting kinda guy, it will seem incredibly boring and tedious, but the system in place actually does promote putting time into each and every craft and trying to earn a High Quality item over just grinding levels.
There is a "Daily" system, but it's a bit different than every day you go out and do dailies, refresh and repeat. They are called "Leve's" and you get an allowance of 3 every 12 hours (and you can bulk save them). You can pick leve's that help boost a certain aspect of the game. You want to level your battle class a bit more? Get a battlecraft leve. Want to get a boost in your gathering? Get a gathering leve. Want a boost in Grand Company seals? Do some GC leve's.
The badass bosses are called Trials. These are tied to personal story a little, so spoiler alert.
There are also Hard Modes of these guys.
TLDR; if you're a fan of Final Fantasy games and MMO's, it's totally worth a shot. If you're looking for the NEXT BIG THING IN MMO's, no. This isn't it. Wait until Wildstar. FFXIV ARR isn't for everybody (as you can tell by the haters).

It's just an instance to kill these bosses. One so far is Ifrit. The next is Titan (fucking hard too). Then eventually Garuda.
