Sorry for having such a bland personality but I want to share how AWESOME chapter 10+11 are. Thematically, these are perfect and unlike anything I've seen in Fire Emblem, almost to a meta level, i.e.:
Gameplay-wise, they were incredibly challenging for me. I admit I "handicap" myself by choosing units equally across all maps, so I had to bench Chloe for this one and had to spoonfeed characters such as Lapis, but the divided front was too much for me and after many reloads, I had the Goldmary front team join the Rosado front in baiting Hortensia with Yunaka, who had 100% avoid against armors. And that was just the beginning (although Morion and Hyacynth were easier).
For Chapter 11 I was in absolute despair. I though I could at least change units, because draging Amber and Lapis around... freeze (i think it's called) was a PAIN, I had no healer, etc. Once I made it to the reinforments I could breathe, but I had to resort to giving stat increasing items to my units for the first time to get there.
All in all, fantastic map design.
