Skills with cooldowns will get optimal damage when using a slow main-hand with high damage and a fast off-hand with similar DPS.

I just assumed the other skills would average the damage between the weapons. I knew that the Primary skills alternated between weapons.

It turns out that most skills only use the main-hand damage. I did some searching and found a good answer on Arqade (StackExchange) referring to these forum posts. I had not really looked into this yet but just happened to see a thread asking about optimal dual-wield weapons for Sweeping Wind builds.
