I don't know, Wint. What I hate myself is, even after having set my weapon-drawn filter to Enemies Only, it still will target those damn carbuncles and NPC's in battle. It's no end of frustration, especially since I use a controller. By the time I get scrolled through all the NPC's and Carbuncles in FATEs, the mob is dead. Really wish there was a way to filter them out completely.
This is EXACTLY what happens to me too!
I hate the targeting system with a passion, it's my number two complaint behind 1017...
