Movie Summary
PTR kill of a silly undertuned boss, good times. This video is pretty much a clusterfuck of a laggy night on the PTR, malfunctioning addons and paladin efficiency getting the shaft. Personally I cringe when watching this video.
The healing mechanic for this boss is quite interesting. The stacking buff you see is acquired whenever you land a direct heal on the person nearest to the large crystal. Whenever you heal the person who has Blaze of Glory (the tank), you get a 15 second buff of 2% x the amount of stacks when healing that tank. The fight is too undertuned to matter at this point, but I forsee this one being an interesting healing fight on release.
Holy Paladin PoV
Also contains a sneak preview of the area that was unlocked after killing Baleroc. There was a short cinematic of a bridge spawnin over a large chasm -which I only caught a glimpse of on fraps-, allowing us to check the areas we'll be fighting Majordomo and Ragnaros later on.
