To FG? Likely never. Off of FG? When SH shut down, it was merged into AB, but I don't think there were any transfer tokens. I could be totally wrong about that last part, but that's what I recall.
Transfer tokens were provided before SH shut down; I moved my only existing SH toon to Skyfire using her token.
Says so much with a question. I don't think SH got the free tokens until there were consistently under 50 people online in game. Start checking those /who all commands. Based on a few queries on EQ2U, I see FG's population has been decimated. If it's dipping under 100 at peak hours, it's not far away from getting the choice to purchase a transfer token off. I don't think it'll be free until the new TLE server is launched. And if I recall correctly, they mentioned a PVP server by summer, so maybe they'll just have that and be done with TLE, unless it's a mix of both. Explains why there's new progression guilds recruiting on live servers starting a lock at 50, though.
I wasn't being facetious, any dev response would be appreciated on when we can expect an option to purchase, or receive free, transfer tokens off Fallen Gate?
