What did I do wrong with Malygos?
Tried to tank him for the first time tonight, both attempts ended in failure because he killed half the raid with a cleave due to a 6.6k rogue taking aggro and turning him back towards the raid. I was told to tank him in the middle and face him 90* away from the raid, with the raid to his side to avoid his tail swipe and cone breath, but cleave got them instead.
If I messed up then I'll own it, and I want to know what I did wrong in that case so I know not to repeat it in the future, but if not, then what went wrong? I did as I was instructed, faced him 90* away and tanked him in the center, and apart from being unable to maintain aggro against that Rogue in the first five seconds, I don't understand how this fight went south so quickly.
