Actually not a problem. Years ago they changed it so that anyonr equipping an AV/AA weapon immediately gets a longer render range. That is why no one complains anymore about being hit by things that do not render anymore. Ofcourse this was then compounded on by nerfing the range of most of these weapons to be less than their render range. I also dont see a reason not to add G2A weapons capable of dealing with aircraft within the infantry render range. After all aircraft get the ability to murder the everliving hell out of anything when they reach 450 to 300m range, why would they not get G2A weapons capable of dealing with aircraft in return?
