If you haven't already seen them Alcast was doing some test on PTS and has done some for his live build videos.
Not a perfect comparison every time due to gear limitations etc. but gives a rough idea what was achievable, I believe he did both light and heavy attack builds for some to compare those as well.

But how this reflects in group content will take time to see. Actual bosses aren't rooted by trap like skeles are, so you have to rely on other people's offbalance for powerlash. In an organized trial (on bosses that can be concussed), i might not even need witchmothers with the lashes I get. In random pugs and bosses that can't be concussed, gonna need many more heavy attacks.
