I remember in the marines we were doing MCMAP training and one of the guys there was being cocky because he was naturally huge and strong. He said to the instructor that he has been in group fights before and he has always won so she pit three of us against him and he buckled like a belt instantly.

The point I’m making here is that you might win a fight with a bunch of untrained randoms but as soon as you start messing with people that have any semblance of skill the risk factor dials up infinitely for each person that joins the fight after.
