Hey. I haven't invested in defensive skills much at all. I put 2 points into Armor. I have played RPG's for years and I always play single-handed weapons with shield. I thought with BD I would play 2-handed weapons for a change. I picked slashing for my hero, and crushing for my DK. I have pumped all other skill points into those weapons. I must tell you that so far nothing has lived long enough for me to need many points in defensive. I have found some awesome 2-handed weapons and even though slower, am quickly killing all comers. We'll see how they do later in the game.
