Hello there. So while I am rather new to ff14 I've been playing mmos for quite a while and I know that picking a awesome guild/fc is pretty much the most important choice you can make to actually enjoy the game. So follows my list of demands

Casual/mature but somewhat focused on end game activities.
Good time zone spread of players. I'm PST time zone usually later on the evening but I do have odd random times I can pop on.
Big but not too big. I'd rather not be alone in a sea of nameless faces.
Helpful and patient.

Look forward to playing with you. I'll be around on game probaly spamming the DF sharpening my tanking skills.
