Gun Sights Need a Rework (Aim Issues, Color Vison Deficiency, ...)

Using this photo as comparison between BF 2042 and BF 4 it's clear what needs to be done. Not only add an option to change ADS reticle color, but SIZE, right now, the red dot it's so tiny that I lose 90% of my gun fights because I can't track the target, this happens a lot of times against terrible players. Also it would be great to add new sights or the possibility of change reticle like COD has, even PUBG has this option. I don't know anything about programming a game, but it shouldn't be that hard.
