harsh oasis
I find it quite useless if third-person accuracy remains very high, as anyone can enable a crosshair outside the game using third-party tools or monitor features, and it's impossible to prevent this. One could even draw a crosshair on their screen. There are situations in close to mid-range combat where you would prefer using third-person view for quick shots due to the higher sensitivity compared to first-person view.
My suggestion is either to decrease accuracy in third-person aim with those rifles or reintroduce the crosshair to make it fair for everyone.
I'd even suggest a decrease in third-person accuracy for all weapons to incentivize the use of first-person view for better accuracy, since currently, third-person view for any weapon is still overpowered but that's a random idea I just like, it mays not work.
