One of my favorite small things from black ops was the lobby leaderboard. at a glance i could see if i was in over my head with the lobby i was playing with. With cheaters and hackers ruining the standard leaderboard, the lobby one was the only one worth while. Does MW3 keep this feature?
Another small thing that i notice they added from blops was the friends button, which i hope works the same way, as in blops it was super easy to join parties, and get parties back together if they failed.
