You have to realize that even for those people who have 71% DD, 7x+ DD is just huge for the game in general, and its too damn much damage reduction, whether you're single or dual-wield. Having DD that high is throwing off the balance in Rohan a lot and is making it really hard to balance other classes further because they need INSANE damage on Ran to get through the DD but then half the damage on Jin to be fair and it's causing a massive roadblock in any overall balancing.
