Aura Mastery in Frostmourne Room

[jackslammer]

I've never considered improved concentration aura a PvE talent or really found the aura ever useful except on shit like Malygos' vortex, I believe it was arcane mages (most likely Extracrispy) that demanded Alyse spec and use conc aura. I'm not sure who needs conc aura but I'd guess staying in shadow resist and saving the GCDs for AM is more beneficial than using conc aura, especially in the Frostmourne room since most casts are instant so there isn't much use for conc aura.
