well to be honest I think Norgannons + Prydaz in 7.1.5 as affliction with MG build could actually be one of the best combinations of legendaries to have.
Prydaz got a lot of secondary stats now and exactly the 3 stats that affliction does love.
I would trade my Rain of Fire Ring and Corruption movement speed ring for those 2 legendaries and pay you 200K on top of that ^^
