You can't exactly scope in with a knife and it'd make the hunter class rather under advantaged if it wasn't there to compensate, considering that as long as you're not blind the other two class' melees always hit and for big damage. If a throwing knife didn't have that hit box range, coupled with the less than great grenades, it'd be a pretty poor class to play. It's probably also there to compensate for lag, since I'm sure you know how bad that could get if you played the crucible a decent amount.

Makes sense that they would have hit-box compensation as it is there primary special melee with that subclass...as long as its meant to be in the game than I'm cool with it...If its an error than I spose that's on bungie as to whether they choose to address it or leave it as is...
