Don’t endermen also stop moving when you look at them? They only atop though, if you have your crosshairs pointed directly at them. It would be interesting to see if this is the same or if it can be any part of your FOV. In that case my use of Quake Pro will come in extra handy.
People just assuming bad faith, I would totally get a “my grandchildren are in my selfish son’s balls” sticker for my parents if it weren’t a wierd thing to put on a car.
