There are a lot of holes in the AI. Post found flaws here.
-Ravinale Guards will not move three squares to kill you unless you are in range of their melee. (they will not attack anything five squares away)
-Nymphs' healing is placed on a higher priority than attacking, so it will spare your team to heal an ally.
-AIs do not account for resistances, so everyone mindlessly attacks Luca even though she resists them.
there is all ready a topic that covers this. Here (http://sinisterdesign.net/forum/index.php?topic=28.0)
Plus, all healers except Ravinale acolytes will put healing before killing.
