Silent is correct. It's the best way to go about it.
Make sure you're running the Sage's 3p set bonus as well for extra DB.
I tested a low torment with Sages vs. a T10 without and the low torment one with Sage's beat out the high torment by far.
Nemesis bracers are also a must, either worn or in the Cube.
Also run through your gear, gems and cube to make sure everything revolves specifically around movement speed or killing elites (If you're doing higher torment, that means sustainability, too).
A good example of a high torment exception to gearing is Henri's Perquisition for WD. It might be killing off a gearing or cube slot, but the first-hit-damage reduction plus charming for 3 seconds allows you to zoom past baddies without getting chipped to death.
