Call of Duty Community: Call of Duty: Modern Warfare 3 - PC...Does Modern Warfare 3 on PC support an in-game Server Browser? Can you also use matchmaking?
"Yes! In addition to the public matchmaking system for finding Ranked public games, you can use the in-game server browser to find and favorite unranked Dedicated Servers to join, which can be filtered by a number of options mentioned above."
So basically, to play ranked games, you have to sit through a lobby, which was the worst part of MW2. Quite lame ಠ_ಠ
I'm wondering though, why am I not surprised at this at all?
