I beat Crota last night, and for my efforts was rewarded with the new shotgun, Swordbreaker. It's a cool weapon, but the abilities, grenadier and last round, are a little lacklustre compared to the abilities or some of the other raid weapons. Looking on the internet it seems like Swordbreaker was supposed to have an ability called "lifestealer" which would recover the user's health and shield upon kills. That right there would've been very useful at the last stage of the raid, and would've made Swordbreaker a great gun. So... what happened to lifestealer? Was it too difficult to implement in the end or something? Will we get it in a later update?
