LFG quirks and problems

I'm still a very big fan of the new LFG system, however, the more I've used it the more I've noticed there are definitely a few quirks that still need to be worked out. A friend in the guild has been unable to log onto his main for three days now because he inadvertently logged out inside and instance, while still in a group when he was finished. He logs in only to be logged back out in about 1-5 seconds. Apparently it's something of a known problem that people have reported here and there in the technical support forum, but that doesn't stop people like him from doing what he did. It's a bug, and as it can lead to days of downtime it's something Blizzard should probably fix post-haste. And that's just one of the problems people are reporting that seem to be related to the LFG system. Can we see a patch 3.3.1 coming soon perhaps?
