Snipers I believe were moved to the secondary slot. The way it looks now isn't too bad though imo. With hand cannons and rifles in primary; shotguns snipers and smg's in secondary, and lmg/rocket launcher in the heavy slot it provides quite a bit of balance between the builds while still allowing the versatility to go either fully auto, or single shot with each weapon slot. Wanna go full auto ? ar/smg/lmg setup should do you nicely, want that super punch? hand cannon, shotty and rockets 5 days. Want that overall feeling of awesomeness ? ar/shotty/anything. If this is indeed the way the system works I don't think I'd be too dissapointed, it will help not only keep the gameplay fresh with each new weapon aquisition but also allow for competative multiplayer to be balanced in a way that while certaint elements have been used we've never seen anything of this depth.
