How exactly are you supposed to get to the -blam!-ing boss with enough time? You have to wait for Ghost to open the -blam!-ing path for 5 minutes. This timed bullshit is -blam!-ing infuriating. Make the nightfall harder, but get rid of the stupid timer. Non neckbeard players don't want to play this garbage. I play Destiny to have fun. Not rage at a -blam!-ing timer.
