Very very rarely.. Let me guess, you had to go against boss noded since they didn't move? Happens all to often with randoms
I won't say I do them every day, but when I have some time, and don't have any energy or another mode to play, I really enjoy doing them. I usually play Random, and I've been burned as well, but I've got a number of great random partner experiences that keep me coming back.PS. I've played with a lot of familiar names from the forums.
