No, Missions are not the only mode of gameplay in districts, there wouldn’t be ramps if you weren’t supposed to jump them, wouldn’t be fast cars if you weren’t supposed to race around, Dump trucks wouldn’t be able to blow anything in its path up if it wasn’t designed that way. To claim the game is simply a hardcore shooter is selfish. And in most cases these “streamers” (we literally all know who you are trying to call out) are waiting for bounties to pop up while they so call “loiter” you can’t discriminate a player because they are not conforming to your rules on how the game should be played.
