If infernal lands between the 2 zones, melee has to be careful when they run out for enfeeble during phases 1 and 2. (just gotta go southwest-ish and away from prince)
Once in a while, he'll throw up 2 infernals between the red zone (tank zone) and melee has to stack on tank until one of them goes away.
Other then that, with this positioning, theres no need to worry about infernals.
Might take a wipe or two, but once you get it down it's free loots
