People abused of macros in perogambit (specially whales), Nutaku announced to mantain perogambit stuff for current event, rushed EG to clean things making event pretty unbalanced.
And i'm not talking about the event gacha issue on this event, Nutaku was selling old N cards in event gacha. After complain Wako is alive again (N slayer card from 3rd EG), but the purpose of the complain was to move her again to N gacha instead of event gacha.
