matchmaking is a combination now. Most players know this. Skill is used with local close to you connections. if the distance or time to matchmake becomes too long they just use Distance Based Match Making. So your entire post is a moot point and wrong. the reason there is sometimes lag is A. cheaters more than you think and B. no dedicated servers. You connect directly to each other so you are having 12 people connect to each other. Its not optimal.
