Twice, I had by myself got to the point where I am transported via "Joining Alies" and am in the purple bubble where I assume the final fight is at hand. Both times I was killed. The worst part of this is that you have to start over in this battle which takes a good 15 minutes just to get to this point in the game. I tried about 15 times to complete this battle in vain. Bungie, you have made this impossible to win with one player and it sucks. What the hell were you thinking? This is the first time while playing Lightfall that I have despised what you have done! Up until now, I was somewhat pleased with this new version but that is no longer. How am I going to complete this Lightfall campain if I can't get past this mission? This was done at Classic level but it felt more like Legend Difficulty. You would think that Bungie would like for players to have a good experience but when you spend all that time just to get near the end and can't complete the mission, that is not good!
