Specifically, you had to have been subbed for 3 months during the last calendar year that 1.x was running (prior to the final 'save date', after which we were able to keep playing, but nothing we did would be saved for the transfer to 2.0). This was announced in I believe February or March, but any days of that specific year you were subbed for prior to that were grandfathered into the campaign.

Any characters that qualified to be transferred, legacy status or no, would receive the tattoo.
