The intended use of Scatter Arrows was to shoot it into a closed space to damage the enemies inside. It was never useful for that, it only ever had the degenerate use of bouncing it off the floor to one-shot someone. That was an unnecessary element in his kit - he should have to land a headshot to do that.
If they were to bring it back I think they should make it so it’s actually meant for shooting around corners. But I think that would be frustrating to play against no matter how it’s designed. So no I don’t want them to bring it back.
