What chapter are you up to, and have you done any of the child paralouges? Some of my favorite maps have been the nohr children's.
I'm up to Chapter 19 and now doing the Children stuff. Doing them in order and finished the Ignatius Paralogue 17, so I've got 3 of the Nohr children now. Ignatius' map was a lot like Chapter 10 for me. I absolutely hated it to start with, but once I figured it out I really really dug it. Sending a small host of units on fliers to go help sure up Ignatius' spot while distracting the big part of the enemy with the bulk of my army was really fantastic feeling strategy. Really tense in cool. Turning that defensive squad into a pincer attack once Ignatius' was even better.
