Pretty much. Or close to it...
It's on one of battles where you have to free the scientists, and the hardest one before the boss has you go up against one Sorcerer and two Savages or whatever. But essentially, 3 Sith.
First, I tried to CC by using the Mind Alter on the Sorcerer and work the other two down, but by the time I get to the second one, either my AOE or my Companion will do some kind of damage on the sorcerer cancelling the Mind Alter and then he just whips my *** with Force Lightning, or I get pounded by one or the other two while I interrupt/debuff his Force Lightning.
And it happens with each companion.
