Here's a summary:
-There are 4 types Heavy, Shoot, Speed and Unique.
-Each character has 1 HP attack at first but learns more as you level up.
-Heavy's main characteristic is a wide attack radius. Speed is high mobility. Shoot is having long range attacks. Unique is somebody that doesn't belong to the above.
-Firion is a heavy-type who specializes in ground attacks. His combo system from 012 is expanded and now has a 3rd attack with 3 variations. Only has one air attack which is Sword Blow. HP Attack is Lord of Arms and EX skill is Blood Weapon.
-Cecil is a Heavy-type who can switch between Paladin and Dark Knight. Paladin is a Heavy-Speed hybrid and DK is a Heavy-Shoot hybrid. His EX is Job change, when it's used he gains extra stats for brief period of time. Paladin has 3 air braves and one ground. DK has 3 ground and 1 air.
-Bartz is a Unique-type Job Master, each move represents a job. He is late-game type character comparable to late-game carries from MOBA and RTS games. His early game is weak but as he masters his jobs (by using a move repetitively) the move is upgraded and he gains a special buff(i.e Dragoon's buff is Defence Up), HP attack doesn't give a buff. His Jobs are Monk, Dragoon, Black Mage, Mystic Knight, Blue Mage, Hunter, Ninja and Samurai. EX Skill is Lucky Charm(?) and gives his buffs to his allies.
-All summons have a bonus effect. Ifrit is Attack up, Shiva is Base Brave Up and Ramuh is EX Skill Recharge up.
Previously announced character's balance changes and director comments:
-WoL's EX Skill is no longer global, has a limited range. Shield of Light stuns opponent when guarding a brave attack.
-OK's type change to Unique instead of Speed. The closer he is to the enemy when using a physical attack the more his EX gauge fills. Vice-versa for magic. This concept was planned for the first Dissidia but wasn't implemented apparently.
-Terra voice is based on her personality after fighting Phunbaba.
-Cloud is strong in separating an enemy from his group and fighting them 1v1. His charge can be dodge cancelled now.
-As opposed to OK, Lightning is still a speed type.
-Y'shtola's specialises in supporting her allies and her spells have a bonus effects other than damage as in FFXIV. Aero applies a DoT, Stone applies a slow and Blizzara binds the enemy. She can heal her allies too apparently.
