Unaware of the entire missing specialization’s, I have Wetwork and Operator as my only two choices. I am 58 (8 points into operator) and realizing I never got my code to my email to unlock the rest. I most certainly played before the 20th. I am guessing at this point there is no hope to get a code?
The codes have been distributed via email and XBL, since you did not receive one you will have to wait until they are unlocked for everyone else which at this time is currently TBD.
thanks, I figured that was the deal. I am kinda bummed.
Query resolved 
Specialization codes have been distributed. For more information on the distribution process, check this post:
