With the recent BR change making the Q-5 10.0 in airRB, i believe it is time for the tech tree Q-5L to be given air to air missiles which it historically used. A pair of PL-5 missiles such as the ones found on the J7D could be carried by the Q-5.
This would probably make the BR change to 10.3, but vastly improve the Q-5 in airRB/SIM and even give it some defense in ground. With the Q-5A at 10.0 missing the air to air as well, perhaps it could just receive the PL-2 and keep its BR.
