A well-rounded warrior who can fight best with groups using leadership and animal taming, having enough healing to keep his allies alive. Can use a horse to fight on (mounted archery) or go into hand to hand combat (swordsmanship).
Better Fighter: If you want to be a better fighter, put more skill into Critical Strike, Backstab, Parry, Dodge, and other combat skills. Better strength, and combat orientated backgrounds (Explosive, Fast Reflexes) would be helpful.
Jack-Of-All: If you want to be more versatile, put some skill points into Special Lore and craft skills; being able to make your own arrows and clothing, or even repair your own items is a real plus. Higher intelligence to raise Skill Caps would be a perk.
Treasure Hunter?: There are enough points left over to take 90 Cartography and 90 Lock Picking.
Bounty Hunter: Take more strength and dexterity. Don’t worry too much about other combat skills. Put more points into poisoning, leadership, and traps. Explosive, Fast Reflexes recommended.
Or just dump all 668 into backgrounds.
At this point, you really should have an idea about what your character is going to be. Backgrounds are something very personal that shouldn’t be described in a guide. They should fit your character, not an ultimate build. Give yourself flaws, give yourself talents. Backgrounds are something you should roleplay, not just take.
