Lots of games have a hide me option.
This was a feature in the late great City of Heroes Game. And it came in handy for the times you just wanted to do your own thing and not be blasted by a billions tells. Or sneak into a PvP zone hit your objective and get out without your arch nemesis heading over to zone to grief you. Or you were secretly rearranging everything in your best friends Superbase
And it would be nice if they offered it here as well. Nice, but not essential.
