So, I'm trying to switch from Hu/Ra to Hu/Fi but during the process, a lag spike occured. The message saying "Items that no longer meet applicable equipping conditions have been removed." but launcher and rifle are still there. And so out of curiosity, I did not unequip the restricted weapons and went to the open field and to my surprise, I could normal attack and throw nades with launcher weapon action. It was interesting as if it was like an all class weapon in base PSO2.
