AMEN. Every night there's about 5 times when the game decides to drop everybody in the room back to the lobby for a multitude of reasons (host migration error, insufficient hosting options, etc). I do agree that Last Chance is a major pain, especially when you down someone, but as they are going down still manage to shoot you with their primary. That extra tenth of a second makes the difference between a kill and not dying, and a death without garnering a kill. Especially more significant in TDM.
I want to see them fix the server issues (to fulfillment) before fixing other aspects that aren't severely affecting gameplay. Another pain in the butt, which was a spawn of the last patch, is the errors when a party backs out of a room. Half the time you will have somebody else's clan tag, emblem, playercard, and even have someone else's mic light up when you are talking...We had such a horrid time getting a 9 man party together Tuesday, we had to split up.
Attempting to play Ground War we were able to play 4 games in 2.5 hours from the hours of 5-7:30 CST. We would either lose people upon entering a room. We would get sandwiched into a game with our 9 plus 3 randoms, making it a 12 on 6 mismatch. We would get into a game and have the host on the other team get disconnected, thus disconnecting the entire room. After 7:30 the servers went back to normal and this happened with less frequency, but still it should not happen at all.
