Please allow us to join all three companies

Don't forget that there will be airships coming so people won't be completely flocking to the Ul'dah company out of convenience. There's tons of people that are going to go to Limsa or Gridania if you ask around.

BloodLotus, I got from that that they would be "disabled" but they are still saved in the event that we can eventually change companies.

はい、なくなってしまいます。
ただし、将来用途が発生する可能性も踏まえ内部データとしては保持されます。
Yes it will be gone, but for future there may be possibility to use them so the internal data will be stored.

FFXI had airships and teleport spells...people all still flocked to 1 city...which is how linked AHs came about.

Oh I don't doubt people will centralize in order to have more access to markets/shouts/etc, but it's much different than picking a storyline you want to go through. ie: I pick the Gridania grand company, I go there to do business, but I still come back to Ul'dah at the end of the day.

Jeuno was the center of the world in FF11 and had airships going everywhere, the other places only went to jeuno so by design it was intended to be where everyone gathered.
