I think that stats that scale with wepon need aditional bonus if you invest in them.
For example:
Strenght-
if you inwest in it, It will give +2X% demage for wepon
and +3X% demage for fists and +x% buff duration.
Dexterity-
+3X% walking sped, 2X% sprint spead and x% atack spead.
Inteligence-
+3X% Magic demage, +2X% wepon skill demage and x% gain focus.
Faith-
+3X% more heal skill efectivnes, +2X% Food healing efectivnes and x% stats bonus efectivnes.
I edit it for beter clarity of what idea I have
For me this bonuses fit in it
