Was hunting tier 1 VNMs in Abyssea-Konch the other night and fulltiming 5/5 just to see. Was also using Plaguebringer for DA, and I didn't notice double damage at proc at all in something like ten monsters, only meleeing them down. Definitely more than one hundred swings, though.
To date, I've been using the set bonus since just after Scars was released and only recall SEEING the proc once.
