Helldivers 2's patrol rates have been a little wonky for a while. After a patch angled at making patrol spawns equitable for solo players (in other words, harder), it was revealed that said update actually just made solo diver's lives just as much of a living hell as a squad of four. Which didn't seem like the intended effect.
Well, Arrowhead games has taken note and is trying to do something about it, as per a recent announcement by community manager Twinbeard on the game's official Discord.
