as nice as apbdb (both versions) are and as grateful as i am to the creators (both of them), all of that information needs to be ingame imo - and not just tucked away in the somehow-still-lackluster tutorial, stats should be easily displayed when guns are in your locker as well as on their respective armas page as well
unfortunately im pretty sure anything like that would have to wait until we get a unified UI, which means probably not until after the engine upgrade
also there needs to be a solid indicator of dropoff ranges, as well as a solid explanation of what they even are - too many new players shooting stars at 80m targets
