Do abilities based on weapon damage take both one-handers into account?

Question

This question is good for finding out how damage is calculated precisely.

However, nobody seems to mention something about this: When a skill is based on weapon damage, does it take into account both one handed weapons or only one of them (the main-hand?).

Answer 1

When you dual wield, you alternate attacks with your weapons. So the damage of your skills will change between each strike. That's why when you equip a significantly lower damage weapon in your offhand, your net damage could possibly go down.
