My daughter and I have 2 wow accounts and 2 battlenet accounts, in the past we transfered several times characters between those 2 accounts without any problem.
We would like to make another transfer now, but what will happen about titles and mounts ? Do you have any idea ?
I made a ticket but you guys on mmo-champion forum might be faster to answer.
You will lose the titles/mounts/achievements on 1 of the accounts(the one you transfering the character from) and get them on the other account (where the character will be after the transfer). It should work the same as deleting the character from the account.
