Excalibur and Hyperion are already so crowded that I don't think many players will be able to transfer in. Originally I wanted 5 of my non-legacy friends to transfer to Excalibur, but now that the server is so crowded, I will be transferring off Excalibur to another legacy server (Sargantas/Balmung), which I suspect are also somewhat crowded.
I don't think SE realizes how many non-legacy players want to move to legacy servers to play with their legacy friends. I'm not saying to let legacy players transfer to new servers, just give us at least one new NA legacy server so we can spread out and avoid server congestion, world full, and their new area player limit.
