Ill note my experience is only on cata but these weapons feel terrible to me. Volley on BH is usable but personally i see it as a worse x-bow.
My sugestion is to reverse the fire modes. Left click should be the multi-shot/burst shot mode. Go ahead increase the bloom for each arrow here. But then the alt fire is a zoomed in single fire mode, with solid accuracy.
The idea is to give it better versatility with a close range burst damage option and an accurate but low damage med-long range option. Something between x-bow and repeater pistol.
