What are you doing MadMilitia! It's AV weekend get out there and get your free ilvl390! Then you too can experience the joy of looting staffs and Shaman tier tokens! (It took me four weeks to get the pally chest)

In all seriousness, after overcoming the 17% hit, having ranged characters for Mimiron, Vezzax, and Yogg would probably be easier for a ranged group. Of course fights where you need to move (Hodir, Agalaon and possibly Freya/Ignis) the melee team will have it easier. And Howling Blast is just cheese as it is.
