Sorry for shite quality no clue how to improve it, was fine in my computer.
We were using 2 demolishers, one shooting up a boomkin and having mage jump out during stuns, otherwise being passenger, other one just alternating between 2 mages. We also had 2 choppers, for tar in corners to lite it up in case we had nowhere to go from hodir's fury, but as you can see we ended up kiting around everywhere so probs could have been done 6man.
According to our RL, it's world first... not sure how true that is
