So my first ramparts run just failed misserably. Gonna try again sometime I guess.
Be sure that on the 2nd to last boss you either decurse that aura or you get away from eachother. It will fuck you every time.
Last boss: Treat him like you would a mix of Rend, Bat boss, and Core Hounds.
When the las pull which are the 2 orcs die the boss will fly in and drop his rider. When rider is at about 20 percent the dragon will land. DPS the rider down asap. At this time the warrior should already be tanking the dragon. Have the dragon point away from your group as he does an aoe breathe attack. During the whole fight watchout for fires that the dragon will spit at the ground. Sometimes they will land under the dragon so make sure your tank isnt an idiot. Fire resist totem and aura arent necessary but they help alot.
The rest of the instance is just tank and spank. Blood Furnace is a bit different though... I wouldnt suggest doing it with a pug group.
