I just completed the Exotic Bounty known as the "A Dubious Task" and was rewarded the Exotic shotgun called "Invective". So far I've noticed the gun isn't very good, there is an upgrade to make [b]the ammo regenerate[/b] however (Like the Icebreaker). The gun has an overall low range and takes quite a while to reload from an empty clip. I may not be using this weapon to its full capacity, any suggestions on this Exotic? Thanks!
