More consistent, sure, but the tradeoff would imply that consistency would come at the cost of lower top-end damage, which is where Juggernauts are currently lacking. Actually, it's not even implication; they flat out said as much in the next line.
From the answer it sounds like the devs are ok with where Jugg DPS is standing. If that is a given, then making players more easily convert their rotation into the best DPS possible is a good QoL change. Reducing the "guesswork" factor of the rotation by increasing the proc chance of Ravage is good imo (and from there they can just rework some numbers to compensate so that Jugg DPS does what BW intends them to do. whatever that maybe, 100 , 200 , 150 DPS below whatever their benchmark 'pure' DPS class is)
