In the current day and age, there is no purpose for base damage in these skills and only serve to hold it back.
Base damage was extremely good back in the age when we didn't have enough stats to beat out skills with base damage, however that day has already passed a long time ago.
Such an example was when there was no way someone's smash could outdamage a Fireball.
What I would propose is instead of having the standard magic formula to become something like
(MagicAttack * MagicScaling + EnchantDamg * EnchantScaling) * Skill Multiplier * OtherMultipliers
(Base Damage + MagicAttack * MagicScaling + EnchantDamg * EnchantScaling) * OtherMultipliers
By changing to this formula (MagicAttack * MagicScaling + EnchantDamg * EnchantScaling) * Skill Multiplier * OtherMultipliers
value is granted through dans, reforges for skill specific damage.
Changing to this formula would most likely also solve some issues such as Meteor Strike being a complete joke since it should have a gigantic skill multiplier compared to Lightning Rod which currently outdamages Meteor Strike as long as you have over 600magicattack.
Base Damage would be great in a world where everyone has 0 stats because the Base Damage is easily over 90% of the spell damage, however in the current day and age, base damage makes up less than 80-95% of the spell.
An example is Lightning Rod
Dan3 has 155-500 base damage
I have 929 Magic attack
7*929 = 6503min
12*929 = 11148max
the "true base damage" is actually 6658-11648 before any charge multipliers or element/combo multipliers
In this case, 500/11648 = 0.0429 which means, the base damage makes up less than 5% of the actual skill damage
I hope KR could one day rework base damage on skills into skill multipliers
