A guildie suggested getting together with AD chars to quest in haderus. When I tried to join the campaign, I got the message, "Opposing faction character already assigned to this campaign." I checked my other alts and found that my DC toon was in there as a guest. But I hadn't played that campaign in quite a while, and it's only a 7-day campaign. I understand that if you make a campaign a home campaign that you would reside there, but shouldn't a "guest" expire when the campaign ends? Even if that weren't the case, shouldn't there be an option to leave a campaign if you were in as a guest. For the life of me , I can't find out how to leave a campaign, and now I'm forced to miss a fun time because the controls on this thing are rigid and obscure.
Unless I'm missing something here, this situation is ridiculous and definitely not player-friendly.
