In addition to the lobby system for custom games, we have added ranked rooms to the lobby system. These ranked rooms will contain pre-set playlists of ranked games which will allow players to earn rank from within the lobby system while still preserving a fair and competitive ranking system. Adding ranked rooms to the lobbies was a decision that was made in response to the feedback given on the forums on and the blog.
Wow, I have to say that I'm really impressed. I knew Slant Six and Sony were listening, but I didn't think this was something that they had any intent on implementing. So from the sounds of it, those "Medley" rooms we all loved in the past games will now basically be the ranked rooms of each lobby. No word yet on how they will break the rooms down (whether it's by map, by mode, random, or all three) but we'll just have to wait and see. Regardless, it's a welcome addition.
But that isn't all. Some more great info came out of the Q&A - no rocket and grenade launchers in ranked games! Also David clarified that all ranked rooms will have respawns off and friendly fire on, while unranked match-making games will have respawns on, friendly fire off, rocket and grenade launchers on. Seems like a fair trade off to me. It also confirms that you will never find me in a unranked match-making game :p.
There is also some more info in the Q&A about how they will handle ranked vs unranked stats, and that they currently have no interest in ever adding vehicles (thank god). So just check out the full Dev Q&A #9 yourself.
