My toon is a dwarf tempest ranger. I put about 50 points in that tree. well picking all of my new enhancements I took fighter kensei focus heavy weapons (which includes khopeshes) also took the next step kensei weapon focus. I also took erotic weapon focus. It said something like if you are a dwarf in wont affect your D axes. SO I thought would be great if I could duel weld D axes + a khop. Iwent to AH to buy a couple of Khop's but the still have the symbol that's say you will get a -4 penalty if you use it.
So my question's are should I now not be able to use khops or any heavy blades for that matter without the penalty. If not what is the benefit of taking these?
