I have found it a worthwhile tactic to just send your PC alone to trigger spawn points at times. Then after the enemy spawns, to run away a safe distance before going to Add Party Members option.
The main areas I found this very worthwhile were in Lower Taris and the Tattooin Dune Sea.
Usually if you had Carth and yourself upon entering Lower Taris, there is a very high percentage of getting mauled

. I find it great to send my PC in alone then run away to the Rodian bouncer nearby (your PC will take some damage) who is basically unkillable and usually not all the enemies follow after your PC. So you can have the bouncer distract them while your PC picks them off with a ranged weapon. Lure the rest one at a time or call in Carth and place him near the bouncer before going solo mode and then lure them in.
The same at the Dune sea. Just send your PC. Once the three tough sand people spawns, cast Force speed and run away until they stop following. Add Party members, go solo mode and then lure them one by one
