Neither of these are very good.

Some general tips.
Scourge and Salted Earth: Always up and on cooldown, respectively and with few exceptions.
Plunge and Low Blow: Try and put these IN Blood Weapon, it's an extra DA-SE if you get both. If you have to hold them for a GCD or two to line it up with blood weapon, it's worth it.
Don't open with Plunge, it looks awesome and showy but its a DPS loss and most bosses you have to move from their starting position anyway. Also don't try to double weave Plunge, use it alone or it'll clip your GCD.
