The screenshot says it all. This weekend was a major stress test and DC was underpopulated in all but the first campaign. Not surprisingly they didn't do too well in my home campaign, and no idea how they did in Auriel's Bow.
The population imbalance might be a problem. It doesn't matter that each campaign has population limits if one faction does not have enough people playing in a campaign, and if DC has the fewest players most of the campaigns will not have enough DC players. It's exactly what happened this weekend.
