I played with alot of the UA members in GW2 about a year ago or so, had a pretty close alliance with them for WvW. Great group of ppl, not sure how many of the GW2 group would be in FFXIV but I know they had a presence in most of the popular MMOs and don't just game hop. If you do join them look for Noobsauce or Bilbo Swaggins they are some of the best ppl I have gamed with.
