it states, that weapon damage is calculated by this formula.
wheredam = 0.3 * (phys_power + totstat) * power * talented_mod
As i can see, power part depends only on base weapon damage, but brings unnecessary complexity. You cannot compare two weapons with 25 power and 35 power without making confusing calculations.power = (sqrt(base_dmg / 10) - 1) * 0.5 + 1
My idea is to show power instead of base_dmg in weapon tooltip. it will not change anything except making weapon comparation easier.
