I think it would be awesome if in destiny 2 or the next taken king size dlc there would be some kind of killstreak like, when you activate rasputin you could choose like 3 killstreaks or 2 and they would be: a big laser like in the grimmoire named and costs 30 kills orso. And when you would do more queen quests, you'd be able to call in a crow ship that helps out. Or maybe even every faction having there own kind of killstreak things
