I wasn't in any of the betas for this game so please forgive me if this is a dumb question. I get that FF14 is an open world, but am I missing something about leveling? I am lvl 15 on 2 classes at the moment, and I "think" that my main story won't let me progress until I complete the first dungeon (Sastasha). I have sat in the duty finder more than a few times trying to get into this dungeon with no luck. I find quests here and there, but once they are gone I am forced to do leves and FATE's to level up (which gets quite boring after a while).

I found a guide that basically says "Once you hit 15, just grind out dungeons over and over" .... so is this what the game is about? Grinding FATE, leves, and dungeons? Are there more hubs with quests I can keep doing that I missed? Do I HAVE to complete Sastasha to get my next story quest and to open up Tam Tara?
