Title says it. Tbh, I mostly feel like 1x is good for CQC but lacks in MR and 2x excels in MR but lacks in CQC. My experiences with the stock iron sights were pretty good since they combine the best from both worlds for me but they're very obstructive most of the time.
I could totally support the introduction of optics with a magnification of 1.5x... IF we change the iron sights and 1x optics so that they simply give the player their sight picture without any magnification.
