As someone whose main character on Live was a DB/WP scrapper, who I also played as a DB/WP brute and WP/DB tank, there's one thing that always bothers me about most Dual Blades discussions.
For some reason, nobody EVER seems to bring up that the Attack Vitals combo followed by the Sweep combo offers three knockdowns with just six attacks. (Plus literal bonus points if you want to add Blinding Feint for the +10% to hit and +30% damage bonuses.) As already mentioned, missing an attack now means the combo will still "finish," which seems like a lot of control -- and damage mitigation -- from a DPS AT.
If you're fighting a tough boss, that means he's too busy standing up -- over and over again -- to attack you nearly as often! Of course, for the full effect, you have to delay Typhoon's Edge slightly until he starts to stand up again, which means deciding between raw DPS or reducing incoming damage.
And with 5 LotG 7.5% and a set bonus or two, you can just stick with Blinding Feint -> Attack Vitals nonstop for fast single target damage, shorter animation times, and that +10%/+30% to hit/damage bonus.
