Plus, people would dupe the living shit out of pets. Achievements earned by the toon you transfer will transfer to the new account, possibly mounts earned by that specific character as well. I transferred a toon a year ago and that's how it worked. Interestingly, I remember having to re-farm the kara mount because the toon I transferred off my main account just happened to be the one that the mount had dropped on when I farmed it.
That said, the process CAN be buggy so you may luck out and get more than what is just on that toon, but it's far from guaranteed.
