Yea, if anything, you don't want to be attracting too much attention to yourself, you're pretty squishy. But, what I've been doing, is sneaking in, open with back blast, hit tab to target someone else, kick them in the balls. At this point you have two of the guys out of the fight for a few seconds, you have stun grenade if they get up too early, thermal grenade has knock back which can buy you a bit of time, but generally things die pretty quick. If there's a tough droid (or two), tell everyone to leave it, and you can incap that for a full minute, which is pretty useful at points on the esseles, and mando raiders.
