No matter your skill level pure connection based matchmaking is what is best for the whole community. Everyone gets what they want. If the lobby is too stiff leave it and try another...unless you are at the very tail end of the bell curve you can find a lobby you feel comfortable in with patience. Doing well is relative. Players with even kd and lower i would imagine will be ok with hitting that mark and occasionally spiking up or down every few games. Strict cbmm or what i like to call, matchmaking will give you the best chance to have an acceptable game regardless of skill level. Sbmm is forced equalibrium, where the highs and lows are lopped off in an attempt to control the outcome of matches rather than trying to provide the best possible environment with which to enjoy the game how you see fit as an individual. Kill sbmm. Anything else is just socialism.
