There are weird things in the arena, especially the fact that top players in the rankings fought the same character over and over ,it's really weird you know for player could fight the same person over and over again. It's really weird to be called coincidence since there are some players which all recent battle is with that one player. Please check this througly either it's a cheat or this game system is the one that lack. You will know what I meant from ranking list and it's recent battle.
