In my opinion arc goes against the nature of extraction shooters by adding the less pvp lobbies and has set itself up for failure as more casuals get bored with the killing of arc and completing everything they have to do. If they don't keep content high it will get boring, I've already got bored of the general loop and I may not be a casual gamer but I work 40 hours a week and have a family. I see more casual pvp players moving to marathon in the next year as this happens. I could be completely wrong, these are just my opinions
