If your character could fly a drake before, it should still be able to fly a drake.
they did change the requirements, there used to be a generic Battle Cruiser skill that worked for all BCs but they’ve changed it so there’s a Battlecruiser skill for each race. When they changed it they gave players that had the generic BC skill the racial bc skill for the ships they could fly. So I have to ask do you have any of the racial BC skills on your character?
Also did you log into the right account? I’ve seen a lot of people come back and they think they have the wrong skills or assets, and turns out they logged into the wrong account. It wasn’t uncommon for people to make a few different trial accounts to try a few different things as a new player.
