For about a month now, between 1-3 of my 5 man team has a chance of respawning alive at the graveyard. This is horrible for instances. That means that they must fight their way back...sometimes alone to the instance door instead of simply running back, or, the somehow the others need to try to come back...either way...30 minutes minimum is gone.
At first, i thought this was a bug with my /script RepopMe(); but, I have asked 3 non dual box WoW friends and they have all had this happen to them at least once. I will check later tonight on WoW support to see what is going on. The problem would be just as bad in non Dual-Box raids as well as they would have same must fight way back problems.
