4th job Single Target DPS

The way chains of hell works is this: 6 dagger hits of 250%, +350% if critical (or more with other critical rings/etc.), and +200% if final cut is active. 6 blade hits of the same. 6 mirrored dagger hits of 60%, no criticals or final cut apply at all, and 6 mirrored blade hits of the same. The 12 mirrored hits are much, much weaker than the 12 original hits. You could also add a stack effect option where the mirrored hits don't apply because mirror imaging can't be used while stack effect is active, or else stack effect gets canceled.

Wait... what? Isn't Mirror Image the same as Shadow Partner? Or are you saying that each of his attacks do 60%+crit damage? Also, when I asked back in the Dual Blade skill tables thread, Joe and a few others had told me Final Cut is 2x. How sure are you of these differences? Especially the MI one.
