So, I bought the Edge of faith on sale...It was significantly discounted so got it. Unfortunately, everything negative comment about how bad the spark is, is true. I attempted to complete the Follow Mission and is bugged. After completing the first boss phase the mission is bugged. I attempted to bring down the bosses shield, turned into a spark and went in the pipe. Unfortunately, the spark will not jump on the platform to destroy the small container to bring down the boss's shield to continue to phase 2, so I end up dying all the time and had to start the activity again. Spent several hours doing this. The spark will not jump, while inside the pipe, to the platform above. There was no need to incorporate a spark into the game, no reason what so ever! And if you do, at least make it work properly...what a messy DLC, unbelievable!!! I think I will stop at the Follow mission and call it a loss. Thanks Bungie! for all the frustrations you brought to your community with this DLC and portal changes.
