Set Party or Use Them All?

[Mr. Carnelian]

I use them all generally but I tend to show preference to characters that are important to that particular plot: using Barret when trekking to North Corel or using Kimahri in Mt. Gagazet or Balthier when fighting Dr. Cid.

That's how I like to do things as well. For example, in XIII I had Fang on my team the entire time I was on Pulse.
