When i created my account i didnt know that there are 3 servers so i play on the wrong server this whole time and all of my friends they play on a different server. Is there any way i can switch or merge my collection like Overwatch? Thank you for helping me.
I think that is not possible. I remember a thread a while ago. Someone was complaining that Blizzard was not willing to move his cards to a different server. In any case, I would try contacting Blizzard's customer support.
Good luck getting a real person at Blizzard. Phoning them its almost impossible to reach a real person. That being said, you may want to just make a new account on the server you want and stop building your collection on the present server.
