SMN should have interesting and varying A.I. thus making party/group mechanics more enjoyable all around.

For instance:

How cool would it be if a SMN's Primal was interactive for the rest of the battle participants?

Let me explain further: Primals/Avatars (whatever you want to call them) in previous FFs just kinda did their thing and bounced. Okay yes we saw some epic cutscenes and such, but why limit the primals themselves to such come n go simple-mindedness?

Primals could offer:
- Certain Weapon skills used by other party members could prompt the primal to follow up with it's own elemental based weaponskill
- Primals could grant party members resistances based on their innate element
- Primals with a defensive nature could physically restrain mobs (a unique stun) for a short period with varying success allowing party members to get heals, buffs, whatever from other casters or just to lock the mob in place.

Just a few examples i thought of.
