Sigh, all this talk between elitists and casuals about enrage method being legit or not.
It' s blatantly obvious the enrage method was a design flaw. It was intended to pretty much wipe a group doing it the normal way if they lacked the dps to kill it intime. They simply overlooked the fact you could wait for the enrage first before fighting. Instead of fixing it and making all the casuals cry out en masse because they can never down turn 2 again, they simply said: "Whatever, let them do what they want for now. We learned our lesson from this and will make sure that in future encounters this method can' t be used.".

So, while casuals might feel like the developers said:" Go ahead guys! We support your method!" they actually reluctantly allow it and see it as a learning experience for future encounters.
