The people that blame the Gjallarhorn nerf on the people that are "complaining" should probably take another look... Quite frankly the Gjallarhorn is most powerful rocket launcher in game at this time and that's because of Wolfpack rounds. If it came down to the exclusivity of the weapon Bungie would simply just increase the drop rate of it or have Xur sell it... Therefore confirming it is too powerful and doesn't fit the play style Bungie seeks it's player base to have.
