After some more tinkering I have discovered that the Kensai paragon path is, so far before any splats being released, the ultimate path for the enterprising Cascader. Everything else aside, he gets the reroll AND a whopping +4 damage! Thats a +4 damage from EACH ATTACK!
So in my above test combat if the ranger had been a kensei, he would have done additional +4 damage with each of the 27 attacks; thats a 108 extra damage right there!
