This "feature" has been confirmed by blue posts to stay for the remainder of classic so might as well go through how it works now. For most people I imagine it'll just act as a passive buff to fury DW, but it does slightly impact gearing as it further devalues hit past the yellow hit cap so I think it's good to understand how it works.
