sorry i swore i responded more recently to this and saw it hadn't been addressed in a while, so here goes:
Tookie and I were playing on Balmung(Legacy) for some time, however we stopped playing for a bit, picked it back up before the expansion, Heavensward, and then it toned down a bit. I still play there from time to time, however there was never an established TA presence on Balmung(Legacy), as its a Legacy server, meaning it was available to players of the original FFXIV to copy characters from to ARR to continue play. I myself had a heck of a time getting a spot on Balmung(Legacy) within the first few days of ARR's launch, and there are still strict transfer restrictions and character creation restrictions in place with nearly all Legacy and other highly populated servers. Needless to say getting a spot on Balmung(Legacy) now is near impossible if you don't already have one.
I personally am part of a small Free Company (guild), as is Tookie even tho he hasn't been around in a while, that is not too terribly different from TA, just perhaps a bit younger, as most are couples either with young families or returning to college, and want a pleasant atmosphere of like-minded people to socialize with and play with from time to time.
But yeah...as far as tookie and i, we kinda ventured into FFXIV: ARR as a side project during LOTRO days, no real aspirations to plant a TA flag, as it didn't seem to fit the demographic of enough of our members, or their schedules.
