Holy fuck, this looks incredible. For context, Fat Shark have been working very hard to address the criticisms of the game at launch, and they've really, really listened to the community in a big way. Many concerns have been addressed already, and the two big ones left were the lack of missions (which is slowly improving, but mapmaking takes time, so I can't be too salty on that one) and the lack of class variety. This looks like it completely addresses that last issue.
Back when the game launched I wrote a review on steam that basically said "Despite all its flaws I enjoy this game a lot and will continue to play it, but I can't in good conscience recommend it." Every now and I go back and ask myself if it's time to go back and finally flip that review to a "Recommended". Every time so far the answer has been no, not yet. This might finally be the thing that pushes it over into a yes.
