#1. New System : Battle Arena

Battle Arena is a leaderboard system in which players can compete with each other over win points. Win points can be earned if a player wins in a battle mode. A group is made of 10 players, and players earn rewards depending on their rankings in the group. Win points will be reset everyday, and another round of competition will begin in a new Battle Arena.
