I just got the myself game the other day, I've been playing it at a friend's house since release and he got the code sent to him, I'm just a little lost on that. Can I not unlock those specializations?

I heard they are going to do rotations of the specializations starting in january, but i havent seen any proof of it. As of right now sr 70 is the max rank for those without the code. If the rotations are true then you do keep the ones you complete is what i heard.
