Warrior %/s (KMS You & I + GMS Unleashed)

JoeTang; According to your table, Lightning + Divine Charge gets increasingly better on bosses compared to Blizzard + Lightning Charge as you get more boss damage.

And in one of your posts in this thread, you said that the latter is superior if the Paladin has no boss damage at all.

So at what point does Lightning + Divine Charge become better? I kinda want to know because this will determine whether Divine Charge goes into my Low Priority list or my Utter Garbage list.

Oh, and if you don't mind, could you explain why such a change occurs?

The order of operations is
Skill_Damage% * (1 + Total_Damage% + Boss_Damage%)

The bonuses charges get when used in succession, as well as Combat Orders and Void Elemental are considered Total Damage. This means that for Blizzard and Lightning Charge, a significant amount of their damage is weighted in Total Damage, compared to Divine Charge where more of its damage is weighted in its base skill damage.

Blizzard Charge is 140%
Lightning Charge is 250%
Divine Charge is 411%

Combat Orders is +70%
Void Elemental is +210%.

Thus,
Blizzard Charge = 140 x (1 + 0.7 + 2.10) = 532%
Lightning Charge = 250 x (1 + 2.10) = 775%
Divine Charge = 441%

This would be why Blizzard and Lightning Charge are superior to Divine Charge in certain instances. However, when other sources of damage are also factored in:
Void Elemental's Total Damage: 30%
Blast Bonus: 42%
Elemental Charge: 25%
Blizzard/Lightning Charge Bonus: 15%
Divine Charge Bonus: 21%

Blizzard Charge = 140 x (1 + 0.7 + 2.10 + 0.30 + 0.42 + 0.25 + 0.15) = 688.8%
Lightning Charge = 250 x (1 + 2.10 + 0.30 + 0.42 + 0.25 + 0.15) = 1055%
Divine Charge = 441 x (1 + 0.30 + 0.42 + 0.25 + 0.21) = 961%

As you can see, the gap becomes smaller. The pattern of attack uses one charge as a primary, and a secondary charge to apply a debuff only. In this case, with all these buffs active, Lightning Charge still does enough damage that using it as the primary attack and only using Blizzard Charge to refresh its debuff and Elemental Charge is stronger than doing the same with Divine and Lightning.

Adding 100% more Total/Boss Damage to the equation
Blizzard Charge = 140 x (1 + 0.7 + 2.10 + 0.30 + 0.42 + 0.25 + 0.15 + 1.00) = 828.8%
Lightning Charge = 250 x (1 + 2.10 + 0.30 + 0.42 + 0.25 + 0.15 + 1.00) = 1305%
Divine Charge = 441 x (1 + 0.30 + 0.42 + 0.25 + 0.21 + 1.00) = 1402%
Divine Charge is now higher than Lightning Charge in the optimal scenario, and can be used as the primary attack with Lightning Charge as the secondary.

Solving 250 * (1 + 2.10 + 0.30 + 0.42 + 0.25 + 0.15 + x) = 441 * (1 + 0.30 + 0.42 + 0.25 + 0.21 + x)
We find that x = 49% Total/Boss Damage where Divine exceeds Lightning.
