Well hunters require the most skill out of all classes. (come at me locks and titans, hunters don't have an easy mode) and throwing knife is a prime example. In D1, throwing knifes had massive aim assist. So now you have to plan and aim your throw. [spoiler]I use nightstalker in the crucible anyways.[/spoiler]
I do like how you have to lead your targets to land a hit. D1 did have a lot of aim assist. But I still think the speed of the throwing knife is a bit underwhelming for a mobility/agility based class.
