I am not a fan of character customisation in games. Not that I have a problem with it being included I just prefer it when all the soldiers on each side have similar uniforms because that’s how it is in real life so it would make the game more immersive. It would be really good if you had the option to turn off customisation on the client side so from my point of view everyone just looks like a generic soldier or insurgent, while from someone else’s view everyone is still a customised soldier. This would satisfy both types of players as ones that like character customisation can keep it turned on and those that don’t can just turn it off.
Perhaps the soldiers and insurgents we customise could appear as the skins for everyone else in this option.
