This was the only fight in these new ops where 16 man was harder. The rest of the fights were completely faceroll easy compared to 8 man. When the power of the masters channel started, we lost 3 dps within seconds before the healers could even react lol.
This happens when people are bad and/or are used to only running 8 mans. With groups that don't require a gear tier above to do 16 man HM or NiM content, there is only one fight that's more difficult in 8 man.
