All I need now is BF4.
Edit: Clicking to claim these in Origin says that they're added to your account, but nothing seems to really confirm that. Clicking this on the website says it requires BF4.
Edit 2: Origin has a 50% off code ("ORIGIN50"). That code brings the standard edition of Battlefield 4 down to $9.99.
Edit 3: The above price isn't a particularly great deal. It's been on sale for $5 at Origin before.
Edit 4:
INTERESTING China Rising, Naval Strike, Dragon's Teeth, Final Stand, Second Assault DLCs are all automatically in my account after buying BF4. I think you
CAN claim them without owning BF4 (which then allows you to wait for it to go on sale again).
This is completely unconfirmed though.
