What do you do when faced with multiple attackers? Im not trying to belittle the style because it have amazing points im just wondering

Although not a grappler, I'd say one does the same as other styles; line up the bad guys, create space, and try to get away.

Barring that, if I was a grappler, and I had to latch on to someone, then I'd go into "snap it off" mode as opposed to "tap them out" mode. But that's just me.

It's not a system that is heavy on this kind of work. However, I have participated in drills working evading two persons standing trying to kick you and working sweeps in. Not unheard of, but not the focus in most schools.

That being said, remember that part of BJJ is standing takedowns, and hence defense to takedowns. This will entail, as all BJJ does, movement and live drilling. That's not unhelpful in this kind of situation.
