I think the one voice I dislike the most is the chairman's... But yeah, from what I've seen, the AI is really good! I kept fighting this one battle where the enemy absorbs fire damage. Though I knew it, since I kept retrying the same battle, my teammates didn't... So Junpei would always try to cast Agi on it first round, shout "Fire doesn't work on this thing!!", and then never use it again. I tried telling him to avoid using SP, but I decided it was better to assign a target to him and just deal with the wasted turn, for that battle at least.

I saw someone else post about another battle, complaining that Yukari wasn't doing anything, just choosing "Wait" each time. As other people explained, that particular enemy was immune to wind (her Persona's element) and pierce attacks (her weapon type). So since she couldn't do anything, she just healed when she could, and used Wait all other times...

And I'm sure the joke about the localizers changing the Evokers to walkie-talkies has been overdone by now...
