If you do this method, you will be unable to log back into Celtic Heroes unless you re-link using the same Facebook account.
You can always submit a ticket to Support if you wish to log-in using a username/password or if you are unable to log in using Facebook.
I got curious and actually just tried it right now (glad it didn't delete my account). It's relinked now but I wanted to know so I can use this method when Google play and game centre log-in become available.
