But we cant really answer that until we see how gaijin decides to implement it, no?
They could absolutely butcher its release and then Pantsir and Kh-38MTs dominance remains uncontested for another patch
or implement 100% true to the reality, and then the door opens for similias SPAA systems for other nations that desperately need it.
Also you cant really add more advanced CAS until all nations have chance to counter it. Look at current situation with Kh-38MTs vs Israel. What is Imp. Chapparal going to do agaisnt Su-34?
