I'm close to getting the assault shield gold. I was playing HC Dom on slums and died a few times after getting a few kills. After I got C4d by someone, the game kicked me and said the session was no longer available. I saw that the other people where still playing, so when I tried to join, it said that I was banned from the session. I didn't think that getting killed a few times in a row counted as suicides.
So you were killed by others and not your own explosives or something and kicked? WoW... if that is the case... then that really is a problem that should be looked at.
I just chalked it down as a one time thing for me since I got my shield gold a few matches later, but I have no idea how far back today i'd need to look.
I don't run claymores or betties. I wasn't even shooting when it kicked me because I was holding a riot shield. I got C4'd and it kicked me a split second after.
This game has you joining Private Matches accidentally. Maybe someone kicked you from a Private Match not realizing they left the door open.
Nope, I was earning xp and got kills for my Shield. Plus, I was in the same lobby for 3 games.
