Clearing this out.

- Legacy members obtained their title by paying for 3 months to play in 2012.
- The Main story rewards, the seasonal events items, Goobbues mount and most items received in v.1 will be transferred. No Legacy membership needed (you were there for the Haloween event, you'll still have that pumpkin head mask from 2011).
- Legacy are getting a rebate on the monthly cost to play FFXIV:ARR and a special chocobo mount (picture above in Shougun's post)
- At the moment, there are no more ways available to get the Legacy membership.
... thank you for calling... ;P
