Rody should be at LEAST Mid...
His growths are as good as Luke's and his bases VERY slightly lower. He should be higher around Cain and Frey because he has more availability.
I honestly think Ryan should move up a bit because his growths aren't too shabby. He's very useful chip damage in the prologue stages and has lot's of early game utility because of the beginning dracoknights and such. Just my opinions, though.
