Place even stats, it's always the best IMO.
I'll also suggest you to choose some CHA based skill, since you have 21
As for feats, how about a multiclass feat for warrior or something sturdy? I'm just delirius here antway. I'll suggest implement exertice for bonus nastiness, and Dire blizzard (Is that the name?) the one that adds damage to cold based powers. Also I've seen that dragonborn racian feats are quite neat for their breath weapon.
suppose I should ask Eblue how many levels he intends this game to cover, as that would affect whether or not I'd want odd stats or reduce them to evens to balance out weak stats more.
Apologies for the delay all, I'll be working on getting some more of my sorcerer fleshed out. I think I'll go with 20's in the two primary stats instead of 21's, spreading my stats around a bit more. Things have been a bit hectic around here and I'm having trouble figuring out what to do.
Eblue: The Frost Weapon, you'll allow it's At-Will to convert sorcerer spells to frost damage?
