I think something strange is going on. As I have been playing today I have been doing well until I get into a lobby with a particular group. They 'glow' more than everyone else and they are next to impossible to kill. These guys are going 27-4 but they shouldn't be able to walk around for the WHOLE game with max armor.
I bumped into this group several times and it was the same in every game. Is there some kind of Max Armor glitch on the PS3?
