Fire Emblem Awakening [SPOILERS INSIDE]

I'm considering starting over,I think Frederick got screwed by the RNG a couple levels with his growths, and most of my other characters are at or pretty close to their base stats. At level 5 Frederick has 31 HP, 17 str, 11 spd, 16 def, 4 res. I had a couple levels where he gained only 2 stats, it was mostly thanks to luck that I beat the first two chapters, and those took a bit of patience.

You want to focus mainly on speed/str/def. Try to focus on getting about 15 speed, then you'll double almost everything. You can also focus on your avatar but it has to be defense spec. And depending on what you want to do with chrom, concerning marriage, it maybe safer to just tie him and fred up until kellum in chapter 3.
