That cutscene at the tower is sweet!
Edit: should I be putting points into warrior or just continue dumping them into dual wield?
If you're planning on going for a 2 sword dual wielder (as opposed to a dual dagger) I would go for the whirlwind branch (starts with dual weapon sweep) first, then the dual weapon line (training, finesse, etc) as they become available. Then you can go for punisher. Taunt and disengage are useful for a double sword wielder because you can run into a mob, taunt, then use your AoE skills like whirlwind, then disengage to recover and pick off whatever enemies survived. I liked the line branch that started with powerful as well, because I wanted bravery and deathblow's bonuses.
Then you have your specialization talents to think about later on too...
EDIT: And if you're putting attribute points into anything but dexterity and strength, stop! Just get ~36 dexterity for your talents and then pump the rest into strength.
