Not killing any treasure bandits

[theatristformallyknownasG]

Couldn't figure out why I never got a treasure bandit even when set to Kamikazie but I have figured it out. I am playing a DH with Companion/Wolf Companion as a skill, when a bandit appears the wolf starts to kill the bandit, trinity sees the bandit as being attacked so it's instructions are complete, but the wolf has hardly any dps. Obviously the main character is doing no dps on the bandit and it always gets away. Is it possible to make sure the main character is always dps'ing the bandit, not a helper or companion ?
