I haven't had many problems with the AI. As long as I cast Libra every time I encounter a new enemy and as long as I cast it right at the beginning, I don't have any trouble. My healers are decent, Cura seems useless right now, but I'm hoping it'll get better.

The only thing I had an issue with were the defenders/sentinel class. Why do they provoke automatically, even if they are the ONLY character in front of the enemy? It seems a little redundant for Snow to provoke when he's by himself; obviously it's going to attack him.
