@EA_Ataashi I have a question about this though, and having the same problem. I wouldn't mind signing into the Dragon Age servers with an old account that is no longer in use (assuming the issue to have something to do with an old Bioware account not correctly syncing its details with the newer EA accounts). But I'm wary of having problems down the line.
I'm just now starting a brand new character, and want everything (Dragon Age Keep, etc) to be properly exported/synced on my EA account that I'm actually using in Origin, so as to be able to import the correct world state data to DA2 and subsequently to DA:I.
My situation is that I moved from a personal Gmail account over to a more professional G Suite account, so I updated the email address on my EA account to this G Suite account. I wouldn't want a second EA account to be accidentally created and associated with my old email address in this process.
Can you please confirm that this is going to work correctly? Or is the necessary DA:O data perhaps being synced through the Origin client itself, without the need for signing in to Dragon Age servers in-game?
