For all those complaining about the AI, I'm making a guide about what each Tactics do. They're listed in priorities order, meaning if both no.1 and no.3 have their conditions fulfilled, it will prioritize no.1. Please note that this is based on my personal analysis, and not completely right.
Also, knocking down with spells mean by Agi/Bufu/Zio/Garu only, not Hama and Mudo, since those don't knock enemy down. Null an element means either null/reflect/absorb.
~Act Freely~
The AI can do anything while in this Tactic. Due to the sheer unpredictability, using this Tactic is heavily discouraged for difficult battles.
1. If there is an enemy that can be killed with normal attack, it will use a normal attack against that enemy
2. If more than one ally is in bad health, it will use party-healing spell. If don't have, it will use a single target healing/item on the one with lowest HP.
3. If an ally is in bad health, it will use a healing spell. If low on SP or don't have any, use a healing item instead.
4. If there is an enemy tweak to an element, it will cast that single-target spell to that enemy.
5. If no enemies can be knocked down with weaknesses, it will proceed to do multi-target attacks (if enemy >1) or the most damaging attack (if enemy = 1).
6. Unknown conditions : Ailments healing, Ailments spells, Spirit Drain, Charge skills, Mudo and Hama spells.
The AI will never : Use buffs/debuffs.
~Knock Down~
In this Tactic, the AI is determined to put every enemy into 'Down' status. Due to the effectiveness of All-Out-Attack, this is probably the best Tactic to use in random battles.
1. If an enemy is weak to an element, it will use a single-target attack of that element.
2. If no enemies are weak to any attacks available, use a physical attack hoping to score a critical.
3. If the enemies null every attack available, even the physical attacks, and there is an ally in bad health, then use a healing spell/item. (Party healing if more than one ally. if not available, priority to one with lowest HP)
4. If there absolutely nothing to do, then wait.
The AI will never : Attack a Down'd enemy, using a spell that don't knock the enemy down, use a multi-target attack*, use buff/debuff.
*There is an exception for Aigis. In some parts of the game, Aigis will have Heat Wave as one of her skills. Heat Wave is multi-target strike-element, and the only strike skill she has at that time. Against strike-weak enemies, she will use this skill to knock them down, even if it means attacking the other down'd enemies, getting them back up again.
~Full Assault~
In this Tactic, the AI will focus on dealing the highest possible damage.
1. If there is an enemy that can be killed with normal attack, it will use a normal attack against that enemy
2. If there is an enemy weak to an element, it will cast a single-target spell to that enemy.
3. If an enemy's weak to Hama/Mudo, use a single-target skill to that enemy.
4. If no enemies are weak to elements available, then use the skill that will do the most damage. The AI will prioritize multi-target skills if enemies are more than one.
5. If the enemies nulls everything, then use a random non-damaging spell (Charge skills, Spirit Drain, etc) or do nothing.
The AI will never : Use buff/debuff, heal allies, cure ailments
