Full auto is a fun option for markers, but it's been my experience that what you gain in auto, you lose in accuracy.
As for outlaw ,as it has been stated before, the rules are up to the owner of the land or the rule by majority.
I have played against full autos, easy to find them when they open up.
I have used full auto, drained my battery pretty quick and disabled me towards the end of the day.
the choice is on you!
