That explains why my Jill had no problem then.
She was my best characters in my PoR power save, meaning she was the one that maxed the most stats (in non RNG mode). Thus, she could go single from the get go in RD, and pawn every units.
I have to finish this game, I'm just taking my time now, approaching the end of chapter 3. Won't make a second run before a long time though.
When I look at my characters, it's amazing sometimes, there's lots of green stats. I have one character which is not 3rd tier promoted (IIRC that's Ike) with only one stat which is not maxed (Luck).
The power save is a good thing, but it's not so essential, as when you start maxing out several stats, your chances of gaining more than 1 stat lessens quickly. You're guaranted to always get 1 stat up for every level, except if you maxed out every stat, but that's impossible at least before 3rd tier.
Anyway, the game was too easy once past the 3 first missions of 1st chapter + the one where you join with Zihark (was the hardest one, I couldn't get everything in this one). Now I'm taking my time, as every chapter is a slaughter, despite me maximizing XP. I haven't even finished chapter 3 and Ike is already level 20, so he's running everywhere unarmed. It's funny, he gets hit perhaps once every mission, despite being countlessly attacked.
I've kept my favorite characters that everyone loves to hate (except Nephenee): Jill, Nephenee, Zihark, Mist, Rolf. I realize I won't be able to bring everyone in the last chapters though. So sad.
I'm split between going with Nolan or Boyd, but surely I will choose Boyd. I think I will keep the three brothers together for the finale.
