its not the best weapon in the game, but I would say it is the most useful. The no backpack perk is great for nightfall/weekly that has juggler and also great for those situations where its life or death when grabbing ammo when you can easily wait and regain ammo overtime. The recoil for ice breaker is awful, but not terribly difficult to control. Although it doesn't have things like armor piercing rounds which are phenomenal, it makes up for with the perk similar to firefly where you can land a precision hit and hits everything around the target, making it a perfect fit with fatebringer when it comes to crowd clearing. As for the sound it is cool, but I actually wish that icebreaker had the sound that patience and time makes because it is a soft and smooth sound with little to no recoil.
