Well, Overseer and Hipshooting Webgun is currently THE MOST broken thing in existence.
FWOOSH and you just ran up 20" into the distance and obliterated any fighter, despite wounds, armour, shields or toughness.
FWOOSH.
So yeah, we made Overseer a one-use Leader ability (for free, take the normal skill) so it's like Warmachine Feat
Especially if your community didn't rule the "Fighter in hiding" rule out (and anything but templates can't shoot at all)
