Frenzy and Backstab Code help please

[The Crucial One]

I was wondering if anyone has gone through the code and made a adjustment to the frenzy and back-stab code to apply weapon damage, the reason im not using back-stab mod and frenzy bonus is its hard to balance it and was hoping to just add a few lines in the code to take in account the Dmg on primary weapons instead....

Thanks for your time
