According to Naver Cafe there is big update on the way with things including the artifacts system (Epic7)for equipping on characters, new Awakening statuses for characters, Tower crawler for collecting unique prizes, Guild Wars, raid bosses for co-op, and more PVP things as well they're also upgrading the combat system to some degree so it looks like they're doing a lot to improve the overall impression of the game which I am very happy to see the effects of in the future. I'm excited!
