First playthrough: Chrom, 'cause I wanted an awesome Lucina
Second: Inigo. I know his father supports are generic, but I felt more impact from the A support when his father was Chrom and it just kinda won me over. (no homo)
Third: Lucina. I originally intended to go MaleMU and marry Lucina for the first run, but I thought I should get a feel for the game first.
Complaints
I don't like the claw things on the Wyvern Lord's shoulders. Every time my Avatar raises her arms, those things make a pincushion out of her head.
Shellfish Knights. That goes without saying.
The neck brace things on Heroes.
Compliments
I thought the Roman numeral design on Sages was a nice touch.
That's all I could think of at the top of my head.
Gerome: I've the face of a sinner but the hands of a priest.
For me, Henry as a Sorcerer is weird because, in his support with Sumia, she says he has little chicken legs. Suddenly, he looks like a bodybuilder. Maybe he's top heavy?
I also had Belquaine. There's also Brirra, Leilde, Rynbur and Phail. I don't have their renown, though. I did find at least one person with FE: Awakening on their DS so I'm not so sure.
Str+/Mag-
Not sure if this will be my final product as far as skills go, but that's where I'm at right now. My only gripe are the claw things on a Wyvern Lord's shoulders.
