Do I need to remember you that there is no limitation of distance between players ? you who follow the news about GRW since the beginning ?
Addind two cameras in the game is not a problem (COD still do it even if I don't like this game) but it works because you have only few interractions.
GRW is designed around many interractions ... too much for too far two interractions (at two side of a camp for example) simultaneously on the same machine. Modern openworld games use the VOXEL technology that is not designed for two big areas only for what is around one player.
