Heroic Morchok Video
So Vortex killed Heroic Morchok a few weeks past, but I just now got around to recording a video for it. It's not the best, but it's still there.
As far as the strategy goes, this will assume you already know the basics.
Heroic Morchok adds more complexity to the fight in the way of a double, named Kohcrom. Kohcrom spawns when Morchok hits 90% health, and will then copy every ability Morchok casts for the remainder of the fight. The two share a health pool, ala Valiona and Theralion. The fight is all about balancing the two bosses casting their abilities and beating a somewhat tight enrage timer.
Whenever a player is hit by stomp, they receive a debuff that causes them to take 100% more stomp damage. Because of this debuff and the double stomps the raid is taking, we chose to split up into two 5 man teams, and tank both bosses far away from each other, effectively creating two separate boss fights.
For each group we have:
Within each group there are:
1 stomp soaker
3 crystal soakers
The crystals still require 3 people, just like normal. However, unlike normal in which you have 2 tanks stacked on top of each other, you need to have 1 person help soak the stomp along with the tank. This needs to be someone with high armor or high aoe damage mitigation. Good candidates are: Sub rogues, feral druids, warriors, shadow priests with glyphed inner fire, and holy paladins (with shields..).
Once you have your jobs assigned, it's just a matter of making sure you soak all of the stomps and crystals adequately, while avoiding black blood during the black blood phase. Repeat all of that until 20%, where the bosses frenzy. It's usually best to hold off on pushing to 20% if possible until a black blood phase, and then popping Bloodlust and trying to push them as far as possible before the phase ends. Remember, stomps and crystals hit harder during the frenzy, so if your soakers are not on their game, you might lose one. Finally, make sure that both bosses die before you celebrate, because if they don't both die, you lose.
All in all, I feel like Morchok had interesting mechanics, but as a difficult fight it was really lacking from a dps standpoint. It was the entry heroic, but I feel it could have done a little bit more.
