This is how my guild's first NM kill went down actually, we spent over 2 hours trying to down him on Tuesday night and called the raid. our next raid day we do NM karaggas, roll up and 1 shot Soa. Everything worked perfectly, no one got owned by landing on a ball, the pillars all actually were where they were supposed to be. Needless to say this 1 shot miracle never happened again. Although, we have since gotten the infernal.
From what ive seem though it seems your best chance for an easy nearly bugless encounter is on the first try. Dont ever ever wipe the fight on a transition phase or you can kiss the floor goodbye.
