I learned this fight where the tank grabs the boss and tanks it at the edge of the arena facing the mob to the outside. Everyone else stands dead center. This is so everyone does not get hit by the fire attack and everyone but tank is already in the middle for when the boss goes into ZOOM ZOOM mode.

Yes no one should just stand there and get whacked in the face but it is the tanks job to position the mob.

Also on the topic of speed running this zone. Tanks need to open their damned mouths when the run starts. They need to state:
Are they speed running or not?
How many pulls?
Lockout or not?

And the biggest thing:
Where are they stopping after a pull. Apparently it is a thing for some tanks to take the first pull of mobs **UP** the ramp and tanking at the top not the bottom like 99.999% of people do. Had a tank get quite vulgar with me (healer) once when we wiped because he pulled up the ramp and left me going "Uh... WTF?".
