Too bad casters will never get it since the melee vacuum up all the scrolls. What an amazing mechanic that was. Worked so badly in Diablo 2, lets copy it!
I can't think of a better place to add epic caster items than in the Necropolis/Orchard quests... farming Tomb of the Shadow King will be very popular.
