A halfling barbarian archer.
At first, used thrown items (Tanglefoot bags, throwing axes, flasks of acid).
Steadily up your str. Then, when your halfling can, get Monkey grip, and a Mighty Composit Longbow.
Basicly, rage for him is the world slows down, except for him; he becomes more focused, and concentrating on the proper strategy, the best place to shoot, the best angle (Max Pain fans will recognize Bullet time! ).
A human fighter. Talk to your DM. after about 2nd level, ask the DM to have something horrific happen to him. He go off, have a little solo adventure, and experience something horrific. His next level is Barbarian.
You see, the fighter is suffering from Post Tramatic Stress Syndrom (Ala vietnam vets). The rages are flashbacks. Something horrific coming up to him, and he has to Kill it, right then, to make the flashbacks stop; they utterly freak him out.
Violence sooths them, somewhat; but the more he adventures (hoping it'll go away), the more often they come (leveling up). Perhaps eventually put him in line for Frenzy'd Berzerker; they've gotten so harsh that He can't control himself, any more. Everyone's an enemy.
A half-orc wizard. 18 int (-2 int) +2 from Spellcasting Prodigy. 18 int for purposes of spell selection and DC. He uses his Staff like a weapon, and after running out of spells, wades into combat wielding it two handed. Considering how you're a Half-orc, you shouldn't have a half bad Str. That +1.5 str shouldn't hurt too badly with swinging the staff.
