I can't confirm then, my setting save just fine. Try manually disabling the launcher via Windows settings.
i prefer to get 20* cuz we will be stronger than KMS players with 25* gollux, lv 3 link skills and attack speed 0.
This is the problem with NA. People only care about their own class and not about the game balance overall. The already weak archers are only getting weaker compared to others with this attackspeed cap.
