Ah, so they DID learn something from revelaitons. Great job, Timmy. Have a cookie.
The main issue with this model of storytelling is that keeping three concrete storylines separate yet related is pretty tough if you try to rush the events, so taking that lesson from the 3ds game, perhaps they could explain certain parts of the story better before leaping into full blown chaos mode.
For those who haven't played that game, they do the three storyline thing there also, which allowed them to bring a variety of situations into the game (claustrophobic horror, all out gun battle, timed escape, escort, survival/endurance) without forcing the characters into contrived circumstances in order for you to experience such a full range of gameplay, while also using the division between these scenarios to limit the amount of stockpiling you can do to try to outmuscle the difficulty, since in one team you can have a whole array of automatic weapons and grenades for dealing with massive hordes closing in on all sides, and then suddenly have to use close quarters combat with the other team while managing limited healing supplies and ammunition. I think it works pretty well.
