With the new GDPR Data Request : Blizzard Login

Just put a request and wait (10min for me).
All characters on your account will be connected even on your banned account.
I get all my mog/heirlooms/achiev from my banned account.

Tested on EU only

Have fun

Edit :

Work with any wow account region but only with Europe, Middle East, Asia and Russia battle.net account

Proof kek.gg (thx to aasda)
