One of the side effects from the buff is that Gnashing Fang + Jugular Rip(580 potency) is now MORE potency than Burst Strike + Hypervelocity(560). Meaning that it is now better to No Mercy before your Gnashing fang and lose a Burst Strike + Hypervelocity than previously when you would No Mercy after Gnashing Fang because Burst Strike + Hypervelocity was more potency.
