My raid put a few attempts on Iskar last night and started consistently seeing the third air phase. The Fel Raven does a fuck-ton of AoE damage though and quickly blows up the raid. How do we handle this mechanic? I figure it has something to do with the Eye of Anzu, but I'm not sure. I watched the Fatboss first impressions from PTR, and on that the Raven just did heavy tank damage, but on live it does a debuff that explodes for AoE damage. Was also thinking of just using heroism for that phase and bursting the raven down.
Advice?
