generally it's:- (at lvl 36)
force charge, savage kick, smash, pommel strike, obfuscate, battering assault, force choke, then alternating between basic attack and vicious slash until smash has recharged. plus chucking in a few shouts and whatever the dual slice thing is that hits upto 5 enemies..
If I'm getting too much heat then I use camouflage as a lock-breaker to deflect NPC dps onto Companion whilst cooldowns clear and to give time to drop a medpack.
if it's really hectic, it's generally "that icon is lit! hit it!"... ...
