It looks like this week is going to go a lot like previous beta weeks -- some problems are fixed, and there are some new ones.
And, just like previous weeks, these issues have become apparent really quickly. For instance, a lot of us are frustrated because we're not able to play with our friends or family because of the assignment issues.
Instead of making us cope with the same issues all week, how about a 24 hour beta test and then switching back to normal? There's really no advantage in running it longer (we're not testing any "end of week re-matchmaking" or anything).
