After you rank up to level 50 you get to choose a specialization. That specialization will determine what kind of player you are and vice versa. What I’m wondering is if after you ranked up to level 10 in the specialization, will you be able to choose another afterwards? And the armor that comes with the specialization, can you mix and match it with other armor variants? And can you use the special visor color on helmets other than the one it comes with? And there are only 8 specializations for the playstyle of certain players. Will you be able to unlock more? In a DLC perhaps?
I would appreciate any answers that can be given by 343i or other sources.
