1.0 player here, but I never subbed during 1.0 (really couldn't justify it), meaning I did not get my legacy Chocobo. I also did not do the quest for the 1.0 Goobbue mount, even though I was playing at the time.

I've got my tattoo and a selection of 1.0 things, however missing those 2 mounts eats at my soul.
