RDM Emperian armor is amazing, whomever says otherwise isn't using it. It's some of the absolute best enfeebling, enhancing and nuking gear available, one of the pieces directly enhances the potency of enfeebles while the other enhances the effect of saboteur. I'm rather happy with our Emp gear, its amazing for a caster set.

The problem isn't the gear, its that every god damn NM in the game worth fighting is immune to nearly every enfeebling magic, the ones their not immune to they end up having a potency reduction to. That and enfeebles suck in general.
