I found this spot at the heroic area on Ord Mantel. All level 9 smugglers. The super weird thing is that whenever a enemy spawns or comes they all start shooting like crazy and the mobs cant hurt them. When the fighting stops they use the Recuperate move non stop. Bioware please fix this.

EDIT: I put a better view of the scene so you can see where they are located
