Look if someone's having a bad time, it don't cost much to throw em a bone. Like sure, that last attack killed them a round early because everyone has had a moment to feel proud today but you. Or like the spellcaster who is feeling a bit shitty because every monster has saved against their spells by some fluke today.

Like if they aren't having fun, what am I doing here?

Video games do this shit all the time. Famously the first GoW gave new players a small boost in multiplayer. It led to a community and better engagement in the long run because people had more fun. BG3 has that goofy 'karmic dice' system, which is on by default. Fire emblem lies. etc etc
