As for the endgame community itself, it is vast and supportive with an array of endgame focused FCs and linkshell statics, as well as the players themselves with the ability to hop into a pug group and go clear T10-12 in one or two pulls. If you're looking for an FC I of course have to direct you to my own: http://forum.square-enix.com/ffxiv/t...uitment-thread
But there are so many companies out there as well!
