I only WS in 9% DA on DRG. Brutal and Emp +2 hands.
Even if you used 15%, needing an extra hit 14% of the time is a 3.5% drop in WS frequency, which is going to be close to a 2% drop in total damage. Consider whether whatever sacrifice you'd need to make to avoid that, since it's likely to cost less than 2% total damage.
