I gotta say it works nicely. I have a friend that stopped playing WoW back in 2006, he has an Old School character... I tried to get it transfered ages ago but of course it wasn't possble... Blizzard told me the same thing... unless names are the same.
Well... last night I tried again, linked his account to my BattleNet account and hey presto
I paid the £15 and got his charater moved to my account and on a different server, also got the name changed. Think was worth £15 for a level 60 old school toon, maxed out prof and old school gear
So this means that if you buy any accounts, and transfer the character to your main account... it will be quite hard for anyone to claim it back
Not only that but if you move servers and also change the name...
I assume it will be a right mess to get an account back and the characters if they were moved and renamed.
I am also wondering what would happen if you link a banned account to your one??? Can you transfer the characters to your unbanned account?? this could be interesting...
