The AK-47 is still good, its just that it has been downgraded several times by Nexon, and other guns beat it in short(SMG),medium(AR, like G36/M14), long(Sniper) ranges. You just need to know how to use it well now that Nexon changed it. You should get a AK-103(or a gold one, really shiny,*stares at one for a minute*)
