If you care then do something for it. Check on video, 30 lvl char may exp without any problem wearing top C weapon. He's not even doing a miss to the mobs. Also, why expertise to D-C-B exists? Why someone should buy D grade weapon? Why armors got normal penalty and weapons don't? Don't tell me some classes can and some others don't. All fighters can even archers, imagine 4-5 people hitting low raids with emi bows. It's unbalanced, or imagine newcomer D grade pvping with a guy on C weapon but same lvl. Again unbalanced. Everything is unbalanced on that, i'm wondering why you let it like that. https://www.youtube.com/watch?v=43egZp61IRg&feature=youtu.be
