I only think they should get rid of the 50 cal snipers. I really enjoy sniping and quickscoping myself. I do however only run with the ballista because I hate spam snipers and I want to use a precision weapon. The DSR can Hit almost anywhere in the body and get a OHK. It does'nt require you to be that precise as the ballista does.
Still it's a game and anyone can use the weapons handed to them.
