I would like to change the line origin x offset (and maybe y as well) to be closer to the center of the screen, since the projectiles are fired from the middle of the head, instead of the hands, which will make it easier to track close targets and it is aesthetically better from third person view.

I would also like this. Hitting mobs and close targets would be much easier with the line originating from somewhere closer to the center, even if it looks a bit odd.
