I just wanted to get some clarification on how the raid lock out system works now. The way I understand it is the decision on heroic mode vs normal mode is made on a per boss bases. Some people in my guild are under the impression that once you down a boss in heroic you can't switch back to normal. Basically, I wanted to know if you say, downed halfus on herioc, would you then be able to clear the rest of BoT on normal or would you be forced to try to down it on heroic?
