I'd give him a 7, for two reasons:
1. No kit, straight fighter. You could have had a Berserker without any penalties considering the equipment you use. While enraged you get: +2 to hit, +2 damage, -2 AC. The berserker at this time is immune to charm, hold, fear, maze, imprisonment, stun and sleep. He also gains 15 hit points while enraged.
2. Grand Mastery in Long Swords. IMHO, there are no really good longswords in the game. I think that the Two-Handed swords are generally better in SoA.
Just my opinion...
