No, pubs supposedly use skill based matchmaking as well. I don't think it works at all though -- if anything, it's dyslexic because teams are always split up very unevenly (moreso than any cod ive ever played);even in Merc Mosh & even in lobbies w/o parties
bigger than a duo.
Actually Kanaye is mistaken. While every Call of Duty before this has used latency/pings based match making, David Vonderhaar, (lead developer for Treyarch) has confirmed that Black Ops 2 does use a skill based match making system in public lobbies, not
just league play. Trust me this has been quite the debate on the Activision forums and Mr. Vonderhaar's Twitter account.
^^I think you are wrong. Unless you have links? I am fairly certain Kanaye has supplied several links stating core pub modes are "matchmade" via connections and LP is "matchmade" via wins and losses ONLY. NO SPM, KD or any other factors.
