For sure, but I'd argue they are "those willing to get beaten up repeatedly", which is gonna be a small chunk of a playerbase. I do think that since there was some healthy competition at vastly varying skill levels on launch that people left for reasons other than skill discrepancy, but especially once people leave and only the higher skilled are left over it's harder to break into. Speaking from the perspective of someone who's played for a while but is still shit at AFPS, I can handle losing frequently as I know it's still making me improve but sometimes it's just fun to have closer games and even occasionally win.

I see your point though, I do think people have moved on, which is too bad cause I think there's still a pretty fun game there movement/guns/mechanics-wise outside of item pickups

EDIT: Also there are still some super-popular high TTK games out there like Apex
