Personally, I'm not the kind of person to unlock the mastery camos every year. If I use certain weapons enough, I'll earn a few masteries here and there.
That being said, I'm most of the kind of person that looks at the camos and I pursue them based on how they look. For example, if there is a solid black color that I can unlock, I'll go for it. After that, I'll be happy and apply it whenever I can.
Does anybody else have the same mentality?
