Similar to the warlock one, except not as limited by a) time (6 minutes on warlock teleport) and b) actually bringing a warlock to the raid.
The only sideback compared to the warlock version is that you're either 9 or 24 manning the boss.
So, heres what you do.
Have someone sit outside the gate, have the raid start the fight, and get someone to put a class wide buff on the class that is outside (ex. Prayer of Fortitude on a rogue inside if the class outside is a rogue). This will put the person outside in combat, and if it comes down to wiping, Professor heads towards the guy outside and eventually resets, leaving you with no lost attempts!
Good for learning the fight if the guy outside already knows what to do!
