Is there a need to level TRUSTS?

From my experience there’s an achievement, and you can change costumes of each Scion members to their respective other costumes. ARR for Urianger, HW for everyone else. I heard somewhere the AI was supposed to get better for Avatar mode, but I’d love to see a tactics menu for Trust.

You're saying that we can pick costumes but it can only be pre-selected costumes? I can't put a skirt on Alphinaud or Thancred?
