Headseeker increases the damage for headshots within the same burst as a body shot. This works great for guns that KICK. Like The Messenger. That gun makes amazing use of Headseeker. You're able miss with your bursts a little bit and still get those two shot kills. However! The Hopscotch has noticeably less recoil than Messenger.... It shoots where you shoot. Like a damn laser beam. You're probably just going to get three body shots if you shoot someone in the body with it, or you're going to get three headshots. In neither of those scenarios does Headseeker make any sense. Unlike Messenger there's really no benefit. Unless you decide to roll a Hopscotch without max stability... But why would you do that? :b Headseeker lets you be sloppy. That's all it does.
