In that specific circumstance I would say clipping a dot is justified. Ofcourse that depends on how many seconds you actually gain by doing it, but in theory, definetly. The reason being, which many does not seem to understand, the dots themselves does not need any damage increase or whatever, you want the 20% from IR and 10% from SS so that your bloodletter has a much greater chance to reset thanks to your trait. And for everyone that thinks multidotting is useful, let me tell you that it is not, it does not double or triple your chancs to gain a bloodletter procc so don't waste your dps on doing so.
