Why couldn't a color wheel/CASt be an option that people could turn off? If they're not accessing it, then there would be no stress on their system. I think it's unfair that those of us who had no issue with the color wheel/CASt in TS3 wouldn't get it back because "some" people have computers that it might be too taxing.
I totally agree there at least needs to be some way to adjust the skintones. They are hideous, I'm truly wondering if anybody on EA's design are a POC, because there is no way that if there were that they would not have complained and been outraged by the horrible skin tones they opted to put in the game, even the new swatches aren't any better.
