Okay, I have had this happen to me about 5 times in a row, and it has helped me alot with the hard fights. What you would do is try to assemble a raid group with some higher ranks and low ranks. You should have at least 3 or 4 people for the best outcome. The lower rank queues in first and everyone else would queue in afterwards. Have one person flag as /afk that is one of the higher ranks. The other players stand there like you actually are afk, and this includes talking and moving your camera around. When the lower rank goes to fight his mob, the higher ranks would then get ported in about 10 seconds after the boss engagement. The lower rank should also toggle /afk when fighting the mob by themselves. Rinse and repeat until you get the rank desired.
I did this on a raid group of 12 and 9 are from my server.-3 people were not afk and those were the lower ranks, and 2 people was /afk, while the 7 were actual standing there afk.
Update;
I got about 14 fights in a row, and it stopped for only 1 fight. It resumed now and i have about 2 fights atm.
