Why do Some Argue Against Skill Based MM?

DeviouslyCursed:  Exactly they exist now, but skill is allowed to make up for it. Under SBMM skill won't make up for anything since it is balanced. So under SBMM those other things like d/cs and stock/OP tanks will have a bigger factor. As will RNG. The more I talk with SBMM proponents, the more I realize they don't know what they are asking for. They think it is some magical solution that will make all matches fun.
