I like a good exotic quest as much as the next person but why would you make it required for the campaign and not put any kind of checkpoints or waypoints in it? I work 12 hours a day. I have very limited time to play this game now and I can't even finish the campaign because I have to get through this and it's already frustrating with puzzles. I'm not complaining about the puzzles. That's not what this is about. Don't remove puzzles don't dumb it down. Just put some kind of checkpoints in please.
