There are 2 accounts linked my email. Those 2 accounts belonging to my brother and I. The one code that was sent redeemed towards my brother's account. At the time I assumed it would just go towards both gamertags, but I recently reached level 50 and still only have 2 specializations.
My question to you all is are they still sending codes out through the Xbox? Or for that matter is there still any way to get a code besides begging or Ebay? I would be deeply saddened if I am stuck at level 70 due to an error on 343's side.
