If you think smg's are still OP at this game then you're an idiot. Small maps? Yeah probably 3 maps are small but the thing with small maps is it makes the engagement against other players fun. Quick reflexes like drop shots, bunny hops and etc is what make this game unique. You want to stay across 50 feet and aim at your target? Then go play bf2, this game is for people who want to have fun. This game is well balance small, medium to large maps are mixed, shotty's are OP if you know how to use it and knows how move around the map, smg's are OP with laser sight at close range. Anything in this game can be countered if you know what you're doing. Should I tell you how I play this game and my play style? OF COURSE NOT! That's for you to figure out how to be good at this game. Need I say more?
If they are planning to put micro transactions in the PC, they need to fix the lag compensation first by providing more servers, I think that's the major problem right now as many people are complaining and they need to address that if they want this game to last very long.
