Bolshka:
Sidenote: All of the dragons are elite mobs, ranging from 70 to 74 elite. A group of five should do the trick, less if you have the firepower to handle it... though it seems a shame to lose out on a multi-drop quest item.
All dragons here cleave, tail swipe, breathe fire, and periodically drop AoE fear. The tail can bop you off the mountainside so stay AWAY from the buttocks region.
Main tank charges in, grabs aggro. Other melee move to the flanks and remain there. If casters stay back they should be safe from harm. Staying to the flanks will prevent the cleave from getting you sometimes.
It pays to have Beserker Rage up whenever it's off cooldown, if yer a Warrior. A Tremor Totem might do nicely as well. Anything to resist or drop the fear debuff!
All in all, not a difficult kill if the tank can manage threat and the healer isn't overbooked.
Oh, and once you get all five scales you combine them to get a RANDOM cloak. It's guaranteed to rock… provided you get one proper for your role. This time around Bolshka scored a spell damage cloak.
