In the past it was deemed an unfair advantage not provided in-game. In the current era we are fighting opponents who have been trained and taught to use them. Theres a recent and very popular video teaching pvp, specifically one video on how to be 'good' at sniping and it tells the players to use crosshairs. That particular video's author freely admits on stream that he uses it. Since it seems to be a widely popular belief it isn't punishable and I am sure some of you might be tired of constantly being disadvantaged for playing fair amongst your sweaty brothers—I ask you now, is it time to put an optional in-game crosshair settings for everyone?
Edit: Also, forgot to ask, please make a hotkey to toggle it on/off.
