Yes but a 0.5 player isn't gonna improve when they play a 4.0 player the gap is too large. It leads to frustration and ultimately not playing. And to that Point a 4.0 player doesn't always wanna play a 0.5 player because it provides no challenge. Sure u could say sbmm means u can never have a game off, but for newer players looking to improve that means more of an opportunity to learn and improve. I like the idea of sbmm for a freelance playlist, simply for the fact that u don't have to deal with stacks and you would play more players around ur potential skill level. Leave cbmm for party play.
