I have 2 characters on one account, and I had to level both to 30 to get the gobbue mount for them both. I was paying for two characters doing that time, so it wouldn't be fair to those that paid for their extra character. Versus someone who has legacy status and expect to have a mount for each free character. If you have a gobbue mount already then why be greedy one there will be those who won't have one.
