Why such bad skins?

I am laying R6 for 2 years now, before i played 2 years COD. I noticed that R6 has really...really bad skins. I mean, they have skin of WW2 soldier while i look in COD they now have Teenage Mutant Ninja Turtles skin, and other really, really awesome skin designs that looks just awesome and i would throw money at them just to have them. In R6 is like...MEH. I really wish that R6 would make nice skins. I bought the halo skins, rick and morty, tomb raider and assassin, all others are just so basic.
What is the reason R6 is not making such nice looking skins like COD does?
