WD weighs the heaviest in this computation formula. You can simply see it as a soft cap or a soft ceiling also because of its strong influence in it.
BRD's weapon damage at every IL is lower than any of the other DPS classes. So 1 point increase in DEX will never see the same benefit as 1 point of increase in STR or INT in melees and casters.
