Full offense is the way to go on the Bombers. Force Pull the bomber in, Force stun, Shadow strike, Shadow strike. Interrupt. Spinning kick, Shadow strike, Shadow strike. Having 9% in Nerve Wracking really helps killing those guys fast. Same goes for the Trandoshan leader guy.
No argument, but even so doing frequently leads to a single Rocket Blast going off for 10k+ damage. Popping Shroud just before pulling blanks that off. It's not like there's a time (other than 3rd bomber) when you'd need Shroud back up again before it would be off CD, so no good reason not to. 3rd bomber obviously you'd just tough it out to have Shroud available for the first Empowered Slash (unless you have 2 Sins and the other is going to be eating it).
