So what happens when you level up skills? 3 things primarily happen.
-Damage goes up
-Cooldown gets adjusted
-Mana cost goes up.
What reason do WA use magic skills? There are only 2 reasons.
So as far as the question goes, the dmg difference between lvl 1 and lvl 20 magic attacks is...very insignificant. However what is significant is the cooldowns and the mana cost. When exactly do WA's use these skills? When an FB roots us. What else generally happens when FB's are around? They MF us. For that reason we setup the skills so that we have a minimal mana cost with a good cooldown. See, pretty simple.
