First, legacy characters had the opportunity by filling in a form, which they were going to start looking at on 9/10. I didn't hear anything back from that on name changes, but I do know I received a vial of Phantasia in my mailbox just a moment after I filled in this form.

When they allow server transfers, they have to introduce code to prohibit naming collisions. When they introduce code to prohibit naming collisions, it is highly likely you will be able to rename in some form or fashion.

1. They just include a renaming service.
2. You can change servers one or two times depending on how this is implemented - may need to create a placeholder alt.

Details still forthcoming.
