Announced via livestream, A Realm Reborn producer Naoki Yoshida confirmed 2 new classes in the upcoming Patch 2.4, Rogue and Ninja. Also announced is the ability for two characters to marry regardless of race, nation or gender. This is rather popular these days in online games, I must say.
A 2nd game trailer was also released for E3 2014 by Square Enix, titled “A Realm in Peril”, which focuses on Patch 2.3. Ramuh (the old sage), 1 of the main summons in the Final Fantasy franchise, takes centre stage here while Garuda, a Titan, and Leviathan are also highlighted.
