I'm getting sick of this game already. In addition to me, several players complaining about this ridiculous BoS drop rate. There was a player who opened more than 100 premium souls and no expressive characters. I only get duplicate and I have never seen red eyes in G / A Soul and much less won 5 stars in the Legendary Soul.
I hope that many players will wake up and stop spending $$$ in this casino that favors the game and not the player.
