How many people get the mythic boss badge?

Games Halo 5: Guardians

Pretty much exactly in the title, because I was just wondering. Only about 2-3 get legendary, and a friend said you get mythic just for helping.
Also because of this vid: MOST INSANE FIREFIGHT FINISH EVER! - YouTube
But if you do know, replies appreciated <3

They adjusted it, like 6-7 get it now instead of 1-2.

I have been in matches where 6 mythic medals were awarded. So at least 6.
