Formulas in RegularSkillCalc for basic skills

It would be excellent to have basic skills formulas in RegularSkillCalc.lua like Energy Ball, Fire Ball, Power Wave, Twister, and so on.

Modifying parameters in SkillList is not as simple as changing formulas in lua file.

Example:

-- SkillID: 8, Twister
function TwisterCalc(Class, InDamage, Strength, Dexterity, Vitality, Energy)
 local OutDamage = 0
 
     if (Class == CLASS_WIZARD) then
        OutDamage = InDamage * 1.0
    elseif (Class == CLASS_GLADIATOR) then
        OutDamage = InDamage * 1.0
    elseif (Class == CLASS_RUNEWIZARD) then
        OutDamage = InDamage * 1.0
    elseif (Class == CLASS_LIGHTWIZARD) then
        OutDamage = InDamage * 1.0
    elseif (Class == CLASS_LEMURIAMAGE) then
        OutDamage = InDamage * 1.0
    end
 
 return OutDamage
end
