This still didn't answer my question about character slots. I have 12 with sub and 5 bought. I wish to move them to the chosen server. On the new server, I have no characters its a clean slate. Will all my characters transfer? If so will I be blocked from making more characters until I delete 6 of them or will I be able to buy more slots once transferred?
Purchased character slots are account-wide. If you've got 5, you have 17 slots on the destination as well. All 17 characters should transfer without buying more.
