I don't know if you can transfer a steam account to my.com. I am inquiring about this point.
But if you delete your character you can create a new one with the same speudo.
of course be careful that someone doesn't take it during this time
Imma just redo the character, Assume its the fastest way but it would be nice to know if that is an option o.o or have them update their steam version so the (Y) store actually works.
Saw now a bunch of posts on steam it does not work properly.... Kinda hit and miss on that one.... sorry to say xD
