Everything in this game have RNG like a CASINO thus the clearance rewards is so poor. Not recommended to download or spend any money for this game. It is totally not worth it at all. Trust me as a player who played since global released. The introduction of Special Battle Badges in the Epic Invasion event causing value depreciation for other contents (BLITZ, OMEGA WAR, DARK ZONE). Poor game content development. Many suggestions submitted but none of it has been discussed and reviewed thoroughly.
