Strikes got completed about 20% faster than usual means it's broken? Could it just be that perhaps TTK content is just more of the same (stationary bullet sponges) so they're nerfing the one gun that obliterates these kind of encounters (which they have no creativitiy to change)? Or perhaps could it be that the new weapons are so lackluster that the only way they can make it grind-able is to nerf old weapons? Food for thought.
