Interesting, from my pov, every afk person in override and strikes is a blessing. Due to the Bounty structure, which is extremely inconvenient, combined with the low enemy density, it always feels like a battle for kills, which is extremely unfun. Bungies dated bounty system which doesn't progress from everything the whole fireteam does, but only counts YOUR own kills, makes it so these activities feel like a chore even more. So you should be happy about afk's. And also, strikes and override are extremely, extremely easy and there should ultimately be a solo option because of that. So i don't really understand your concern. Afk's in pvp comp mode and gambit are a whole different story tho, those people should be detected and suspended more efficiently.
