>remove the gore
>FIX THE SOUNDS!!!!!!!!!! and bring back a lot of the old sounds that were sharper and louder for the actual gunshots (better distance sounds is nice)
>tune the guns better
>bring back the animations and whatnot of the old system
>fix little cosmetic issues (invisible slings, rifles being oversized, the straight vertical r870 that just exists on your back)
>rethink who gets what (why does every le dept get the same gucci'd-up cagster rifles. bring back the sd in the sticks getting just the ar15 with eotech or irons for example. city pd does NOT need an m110)
