I actually haven't had any issues in MCC so far, and I dunno how. I've been matching into games in about a minute (which is how long Halo has always taken for me). Hopefully it starts to improve for everyone else, too!
@roomrunner: If Daniel Bryan isn't back by Rumble, I would be surprised. At this point, Daniel Bryan and WWE have both been saying that he needs to be checked out again to see if he needs one of two different surgeries. That has been going on since the middle of July. In the world of sports medicine, you don't wait four months to decide on a surgery. Broken spines, shredded ligaments, torn muscles, doesn't matter, the surgeries get done ASAP.
Daniel Bryan is a top guy in the WWE and well-liked by management, he is getting the very best treatment that money can buy. Maybe that somehow isn't enough, but with the recent report of him training at the Performance Center, I wouldn't be surprised if this has been a work to make the surprise of him returning a whole lot bigger and better.
