I hope, this issue hasn't been discussed before, I couldn't find something referring to this.
My 10-player raidgroup decided so skip Ascendent Council heroic to do Cho'gall hc because of setup problems. After killing AC on normal mode, 2 charakters got droped of the group and two others, who didn't kill AC this ID before (Halfus and V&T hc have been killed with the same charakters as used for Cho'gall hc). Now, the problem is, the raid ID can't be switched to heroic mode with the 2 charakters in group wich haven't killed AC. Either Cho'gall has to be done with the exact same setup as it has killed AC that ID, or he has to be done on normal mode. We tried to reset the ID, disbanded the raidgroup and reinvitet and all the other stuff u had to do in vanilla to reset a dungeon. Is someone familiar with this problem, ever got an answer to a ticket referring to this or got a solution?
