The japanese version is almost two years ahead of global, which is to be expected, but there still remains the fact that while japan is showered with new units, new events, and new ways to grind for resources (free crystals for summons), global has been beyond shafted. Useless units released outside of their events, no story progression, and only paid opportunities to progress. Hell, their 4th anniversary " appreciation" gift to us is the top 20 units in the game hidden behind an $80 paywall.
