Yeah I could never do that. I need to see them in story segments, use them in battle, and compare them side by side to other characters. I often do some prior research and sometimes it informs my decisions (especially for Fire Emblem games), but I need to see characters in action before I can decide if they're worth using or not. For example, I was pretty set on using Argilla, Serph, and Heat for the entirety of Digital Devil Saga, but I liked using Gale and Cielo during the cruise ship dungeon so much that I stuck with them for the entire rest of the game. I went from being anti-Cielo in the early game (before you can use him in battle) to using him almost all the time.
So yeah, Inquisition. I have no idea. I'm not even sure what race, sex, or class my Inquisitor is going to be. That'll be at least three hours at the character creation screen(s).
