Why this big nerf?

On the change log of August 3 you changed the proc rate on Berserk enchant of ferals

Fixed weapon enchant proc rate being based on the weapons attack speed rather than the ferals attackspeed while in feral form

But this is ridiculous:

there is no reason for Massacre to outperform Berserk, should we pick fast staff over polearms now?
I would love to see some documentation over this changes, you pick some logs from classic?
I will remember that slow weapon user like paladins still got 60% uptime on berserk

You dont only nerf berserk, you nerf all the PPM enchants (Executioner, Moongose) so you have to put it in the changelog
