There should still be free character transfers available, I believe you have to use the shop button on the character select screen, and there should be an option for free character transfer in addition to the paid ones.
If you are on Windseeker and alliance I’d reccomend Pagle or Atiesh. I’ve been on Pagle since 2019 and can say its a great server. Don’t be turned away from the “full” mark, not been any queues. If you are Horde Mankrik is the way to go.
