Not sure if they “should”. But: not every gamer can play PvP. Some people have deficits and illnesses that prevent them from even having a slide chance against human players.
You want that your game can be played by people, regardless of physical condition, or by the elderly (and in sense of games this means 30+ sometimes)?
Than yes , yous should provide such a node of you already have some vE in there. Of course , multiplayer games are multiplayer games.
But this is the same conversation like “should games have an easy mode”
I personally would love to play for example the eldenring series, but I can’t. I am physically not able to play the game with the required precision. And let me tell you, seeing arguments like “learn to play” are hurtful.
So, maybe consider this side in further arguments
If there is a second mode, how do I influence other players negatively?
