While i do get goofy approach FC series has, i sure would like additional outfits that have real world military gear look approach to it.
Military camouflaged uniforms, vests, proper helmets, ghillie suits etc, would be great and not just having access to wacky unreal outfits. While i have nothing against having Steampunk/Fallout 4 "Raiders armor" style of gear to wear. I prefer to have more real life visuals on characters, in FC5 I only had my character wear "Scout Outfit" mix with "R6 Armor Pack Outfit". Even though it's just visual, I like that it looks something I and anyone else would wear in real life in war zone.
Having 3rd person camera in camps and looking what wacky outfit i must wear, kills my immerson.
