Guild Wars 2

Does substituting your effective power for your actual power in the skill damage formula give you your average damage, or should you always calculate skill damage and then include critical damage after the fact?

The formula for effective power is (Power × [1 + Critical Chance × (Critical Multiplier – 1)] × Damage Multiplier). Because this includes crits, I would think that you could simply say ([Weapon Damage x Skill Coefficient x Effective Power] / Armor ) and arrive at the same conclusion as the usual ([Damage / Armor] * Crits) for your average damage. For spreadsheet management, using effective power is a bit more efficient than the latter.
