Arenas
Like others games, with a weekly reward for being in top 3 of the week winners, 1v1, 2v3, 3v3.
CH > Join a 1v1 arena > waitting to enemy > If other player clic it too you faced
Party 2/3 People > One player of the party join arena 2v2/3v3 > if another player with a team clic it too you faced. (Ofc all members need to accept for start the match)
Excelent idea!
