Sniping headshots from 100m away has to be the most annoying challenge I've tried to do in any game ever.
It forces me to abandon my team to camp locations and not actually play. I dont want to do it but I want to finish the campaign so I find myself camping extractors and bot locations praying the enemy stays 100m away all while contemplating while I spend so much time on this game and why I even play it.
When you give people challenges that make them want to pull their hair out thats not player retention.
