Thank you for your feedback regarding the dog killstreak. I will continue to gather more cases of this occurring for our players and forward them up to our studio.
While I know you stated it not your connection, I would still like for you to set up port forwarding, and do some basic troubleshooting to ensure that everything is good to go on your end.

In terms of the theater, this was a decision made by Infinity Ward. This can also be a suggestion that I can forward along to them! You never know what could happen!
