You shouldn't be using it with blood price in the first place. It's best to rotate between the two to avoid situations like the one you're suggesting.
Also, people tend to under mind the usefulness that DA + DD brings. A 20% chance to evade ANY incoming damage? Evasion is the best form of mitigation in the game (outside of Pld's HG). And it's only 20% of the time (so around 1/5 attacks) so you most likely WILL be getting some of those incoming attacks to proc reprisal and low blow's reset. And you'll only be able to get off 1 reprisal during the duration of Dark Dance anyways and that's assuming reprisal's CD is about to end. All in all Dark Dance is a VERY solid ability that people tend to overlook as not all that good...but people also forget that the 20% evasion applies to both physical and magical. And because of that it can be said that every defensive CD that Drk has can, in some way or form, mitigate any and all magic attacks, which is also what makes Drk the best tank in terms of magic mitigation.
