So I was playing wow and I was doing the black temple and right before the last boss the raid leader just kicked me out for no reason. Now I started this raid group and he only asked to be the raid leader so I trusted him. Now I invited this random person to a raid group so I could enter it again and when I did I get a message saying 9/9 bosses defeated. But under raid info it says that Illidan stormrage is available. So now what do I do. Is there anyway I can defeat that boss without have to redo the entire raid again. please help me.
