Before you go down that road, I will add that there is often time in the rotation for ST attacks to fill with Boggle.
Telekinetic Blow, Assassin's Psi Blade, Greater Psi Blade are the primary ST hitters to rotate with. Fill in holes with Placate, Concentration, and Boggle as needed. To me, Boggle is an opener - cast it on the Pylon prior to engaging (it doesn't notify mob), have that added Insight chance in the pocket and then carry out the normal attack rotation.
A great breakdown of Scrapper Boggle Insight chances from @Replacement below (and link to thread):
