Blunt weapons will still be effective with medium PS (especially staves and spears, which are incredibly fast compared to pretty much everything else).
Problems with cRPG lie deeper than agi/str balance. Taming athletics will help a bit, but generally biggest issue is the omnipresent melee fighting style which revolved more around circling and spamming attacks than actually picking best timing and direction of the attack. That will never change, but it is way less pronounced in native due to slow movement speed.
Hope that for new game, there will be a mechanism that will fix that in some way.
