Yeah it has done this to me since 1.7 came out, no idea why it does it. Removed Assist from every one in the raid and still does it, so now I put on pets.
Ok for one Battle.net is the Road, the Players are the Cars, and Oqueue is the Pot Hole, lets all be clear about that. I run absolutely no addons except Oqueue when I am puggin cause the addon is soo buggy. When I finally find a good group I say brb log out disable Oqueue and continue raiding the pug. I dont mind Oqueue being the pot hole on the road, as there are many pot holes on the roads but we all need to get to our destinations. But for you guys to blame Bnet or other addons is bogus. I use the hell out of Oqueue, and I will continue to use it and tell other to DL it from your site, but there will always be the disclaimer that Oqueue is very VERY buggy and has crashed my game, cause me to connect and disconnect from Bnet which has cause raid wipes (again excusing my self while I disable OQ). But let it be known that when my OQ is off I never experience crashes nor Bnet log on and off lag. So there is def someting wrong with your addon. Unfortunately you are the only addon that I know of that puts groups together with ilvl and raid xp in te info tab, so Im carrying a few extra tires in my players car while I drive down the Bnet road, all the time trying not to get a flat tire when I hit the OQ pot holes.
