I can respect that. I basically came to the same conclusion regarding most PvP games/modes.
If I'm playing a game to have fun, and I'm not having fun, why am I still playing it?
My online friend group never really saw it my way unfortunately, but it always amuses me when we hang out in voice chat and they're getting biblical-levels of salty in a match while I'm just chilling and playing Spyro or something.
That being said, it sounds like she'd effectively turned the game streaming into her job. That'd sap the fun out of anything eventually.
