The new raid is really good, the best since VoG I think. The new social area and new patrol areas are also cool, and the enemies too. The story missions are fun if not groundbreaking, a couple are quite challenging.
But, there's not a lot to it beyond that IMO, and the grind to reach raid levels is really annoying. Weapons... you've kinda seen it all before, not much new there. Worth every penny for the raid IMO but doubt it'll keep my attention for long. (The raid which we didn't quite manage despite literally playing all day yesterday. We weren't quite doing enough damage to the last boss)
