Screens look nice, but please don't make the same mistake a certain other developer did in moving too far away from the golden mechanics of RO1/DH. Gameplay is king and recreating these mechanics should be your main focus, imo. A slower, thoughtful, chess-like symbiosis of timings and distances while keeping all of the players' avatars equal in terms of what the avatar can do (run speed, sway, entering/leaving ironsights etc), and leaving the difference between success and failure up to player skill. Leveling, zoom, spawn on squad leader, spy planes, peripheral indicators, flashing lights on the edge of your screen telling you where shots are coming from, client-side hit detection, radar, arcade-style speeds, inability to leave tanks, avatars giving an unprompted dissertation about their current mental state, ranked servers, too many game modes (more than one is too many fyi), I could go on and on - these things need not apply. Mantling, bullet penetration, smoother MG mechanics - yes. All that other stuff - no thanks. In this case, less is more.
I hope you guys feel the same way about all of this. All it takes is to take a step back and ask yourselves what it was that made Ostfront/DH so popular with so many people. At it's core it was the non-hand-holding skill based gameplay achieved through a tight set of mechanics not bogged down by a bunch of erroneous 'features'. In addition to that, a more accessible means of adding content to the game via the community, and a comprehensive set of tools for the clan scene (both grossly underestimated) would go a long, long way.
This isn't to say that new features are unwelcome. Quite the contrary. The main concern is staying on the same philosophical path in terms of creating the gameplay we all know and love. This is achieved by tackling new features one at a time in close collaboration with your community over a period of time. What you don't do is add a dump truck full of half-baked ideas all at once without any significant community involvement, which then forces you into damage control mode because of the inevitable backlash when those ideas don't make for a good game.
Best of luck guys. We're all on bated breath hoping you come through.
