I remember in 2020 they have a pre-PTS (Not sure what to call it tbh), where Zenimax tested light and heavy attacks in hopes of changing it and making it work for newer players. This was done back in March 2020 and by the 4th quarter with the introduction to the Markarth dlc, they made the changes to light and heavy attacks with regards to the earlier PTS testing period in March.
I don't understand why you would go from there to where we are currently, but I am giving you the benefit of the doubt and hope making light and heavy attacks flat values actually achieve what you are trying to do. I have no idea how much the flat value is but it better be decent and not just outright nerf light and heavy attacks at that
