People standing in a heavily obscured area or with total cover in relation to the opponent CAN HIDE. It's that simple, really. This shouldn't be up for debate.
You can't see things behind a wall or in total darkness.
Yep I'm talking about sniping and then trying to use your bonus action to hide in the same place repeatably.
Or the Halfling hiding behind a medium size creature. That trick will work once. Otherwise you're getting a poor man's greature invisibility at will.
