The issue you seem to be describing is not the job being too good, it is the job being used incorrectly. Droids are there to generate RP without a GM being needed or to add to the RP of a scenario. Droid jobs are not meant to be used for the fun of the user only being used to kill, if this is happening a lot give me the names of who is doing it and I will take their whitelists away. For now consider this suggestion denied.
I'm on mobile so sorry about the format, @0zzy Lock and Move please.
