Shield Swipe is currently still a DPS gain. If you haven't noticed, the DoT effect of Goring Blade is unsynced by an entire GCD. Placing Shield Swipe in there will see an additional 40 potency tic. This limits you to an average of +50tp every minute, any additional shield swiping will result in a loss of potency. I would not be against seeing it boosted to 230(Royal Authority avg), but only if DRK was given a similar enhancement to their TP management, considering the benefits of Bulwark & Sheltron under this boost.
