+ Deflection on hatchet is very good for tanks, DR reduction, accuracy and reach are probably my favourites for the rest, regarding choose best damage type weapons i think the bonus is often useless - you can instead switch to a single damage type weapon that best suits the situation and that has a bonus on top of that, you just need to scout ahead. I can however see the advantage of dual damage type weapons later on when you take specialisation talents and you start fighting more enemies who may have different types of DR, you probably want to stick to a specific weapon at that point.
