Would Duality working with combo effects be a bad idea?

[MrCookTM]

Why would people have to use Duality on Armor Crush?

Because that's the proper way to do it, as using duality on your next armor crush is a dps increase over holding it for your AE, unless you would AE combo right after AC (aka you don't have to mutilate/SF because they're still running and don't fall of soon), in which case holding it a few seconds for AE is worth it. Shasta's guide has the math for this, if your interested. Also having enough time on your huton doesn't really matter, as long as you don't use AC with more than 40 seconds left on huton, the amount of AC's/AE's you do doesn't change.

On the topic itself: I like the idea of duality AC giving more huton uptime, but the only thing that would do is increasing nin's personal dps, which is not needed. Nin is already highly wanted for every progression group, and nin doing more personal dps as it does right now, would probably fuck with melee balance pretty hard.
