With faction balancing, the locks come and go as people filter in. We’ve had a few people make new characters within the last few days having to deal with the locks and it roughly takes about 15 minutes of refreshing the creation list by swapping to a different server and back. It’s a hassle, but it is possible if you would like to try.
That said, I don’t know if it would show or not accurately if you already have an Alliance character made, so maybe keep that in mind! Would hate for someone to delete their character and then get SoL when trying to swap to Horde. Regardless of what you do, we appreciate the support!
