Pure Strength = Easy mode
18/18 = normal mode
Pure Agility = hard mode
Sir Tankmen, the Grandmaster of Order of the Lance, wrote this about a month ago, and I agree with him.
You can read the original post of his by clicking on the quoting link, more detailed info and discussion over there.
One thing I'd like to add is:
With more Strength, you can wear more varieties of armors, which means more roles to play as (Ninja, Samurai, Knight, Nordic Warrior)
Of course, you may see a light armored knight in tourney outfits, or samurais in their casual practice outfits, but they tend to give less immersion of the role a player plays since the general impressions on those roles would be heavy plates or gusoku.
Sorry, derailed from your original question.
2H / Xbow?
Strength: 15
Agility: 24
Hit points: 54
Skills to attributes: 8
Ironflesh: 2
Power Strike: 5
Athletics: 8
Weapon Master: 8
Two Handed: 113
Crossbow: 150
Armor: Studded Leather Coat, Kettle Helmet, Leather Gloves, Rus Cavalry Boots
Now you can be a sniper and put up a fight in close quarters as well.
And please note: I've never played an infantry 2H / Xbow before! If anyone else would give a much better and practical advice, I, myself, would be appreciated, for I'd like to know how the build should go.
