I myself are still stuck at chapter 10 in my Nohr-Run, because I just kinda ... well, put everyone except of MU in a corner and looked, what happened. First Chapters were easy, from chapter 5 and upwards I used to not even take Elise onto battlefield anymore, because she was more a pain than a help. (Not to mention Aqua, but at least I got her out alive, so she can stay back like everyone else.) Did some pairups via MyCastle just for fun and had no trouble recruiting the kids, since MU didn't take any damage at all. So, after a lot of maps that I just finished with MU soloing everything, I stumbled into Chapter 10. And yes, I DID realise, that I might have a little problem defending 4 tiles with just one unit. Tryed it at least - MU is not getting any remarkable damage but hell, there's no way I gonna get that done. (Did you know, that the enemys don't dare to attack you, if they would deal zero damage? They just walk straight up to the files you try to protect. ~.~) It was fun so far, though. I would've never thought, that I could get that far with only one Unit in Nohr/Lunatic.
