I think one of the main reasons some people think that hunter is too powerful can attributed to his crossbow's arrow spread when unscoped. The crossbow is essentially a (more difficult to use because of travel time) sniper rifle. Most of the sniper rifles in the game have a HUGE bullet spread when unscoped that makes it borderline impossible to hit anyone, even at close ranged, when unscoped. Meanwhile, the crossbow's unscoped spread is still very accurate, making it spamable when an enemy gets too close to you. I think that increasing the unscoped arrow spread at least a little bit would keep it from being spamable at close ranges.
