In preperation for Cataclysm, our guild is attempting to start work on obtaining legendaries from Classic and The Burning Crusade. This means, in part, doing a run at Illidian as often as we can pull one off.
Having never raided in The Burning Crusade, I'm a bit unclear as to what bosses we have to kill to get to Illidian. From a brief glance at the map on Wowhead, it looks like we can skip most of the instance, going directly from the entrance, to Supremus, then to the Den of Mortal Delights, killing Mother Shahraz and the Illidari Council, then heading to the Temple Summit to kill Illidian.
Is this right? Or is there a portal / door somewhere that doesn't open until we've killed all the additional bosses as well? For example, in ICC, it is impossible to kill the LK without killing the end-wing bosses. (And it was similarly true in Naxx before that.)
Any advice on this front is welcome.
