In the quest "Finish the Job" for the tb dailies, if you attack and kill the restless infantry first, the restless soldier will turn around an attack you, but will also have full health. to avoid this, use an AoE before you begin to attack either of them, attack the restless soldier first(but dont kill him, just a bit of damage is needed), and then attack the restless infantry(kill him, then kill the soldier). Makes things a bit easier imo.
