Because other people are casual and don't want to spend a game with others that destroy them. Going into a game with a 6 man team all using the most powerful weapons and spawn trapping you is not really fun if you ask me. To that, I don't say "nerf snipers", I just want to play a fair game. One time I went in control against a group of people that were spawn trapping us and using the best weapons. I was so angry, but then I popped my arc blade in B, and cleared out 4 enemies, and captured that we couldn't capture for the whole game. We didn't have enough time to make a comeback, but it was satisfying as hell. So in the end, try hard games are inevitable, but don't let it stop you from playing a game all the way through
