People who play Arena go AFK and not get kicked are trolling and needs to be stopped.
It is really frustrating. I never liked getting booted from searching for a game simply because I’m not constantly pushing buttons, but now people go entire games afk which shouldn’t be possible.
There are people in Halo 5 who do this as well. I think it is more a gaming issue then a Halo issue. Still, it should be punished.
