Can anyone unlink their steam account? Mine's grayed out
You can't unlink an account that you are logged in to Bungie.net with. You would have to log in to Bungie.net using one of the other account credentials and then you should be able to unlink it (unless it is your only account)
Nah I think it's just fuq'd. Logged in PS4 can unlink but Steam is unlinkable.
