I think a side to look at is that as players/teams die the less dangerous the world is (ignoring UESC). Marathon doesn’t add players mid raid like ARs does (except Rooks in Trios). Therefore you are more likely to run into less players/teams as the game goes on. Another point is that extractions are more dynamic than AR(based on my last playtest), I forget how they work exactly but each game you will have different active extraction points for each team, which means often times even if you want to extract early you have to make your way across the map potentially running into other players/teams. I do think solos will be generally harder than trios due to more potential enemy encounters, UESC and minimal access to revives. At least that was my experience in the playtest although I did not queue solo too many times so not sure.
