I've still gota while yet before I rank up to use any the specializations, despite my already having LE and I see all of them with a lock symbol which I'm not 100% I really understand . (I know you obviously can't do anything with them until you reach rank 50....) What I started wondering since a lot of people have already gotten to some of them by now, as with the other pre-order bonuses....Are all the reserve (preorder) retail exclusive skins maybe assgiend to and unlocked through specific specializations? Any idea? Leave me a reply back. Thanks!
