For me it doesn't make sense that the styles themselves are just fluff. There could be just a list benefits to chose from (5BP / 10 Karma each) and it would have been the same. Also, the fact that there are more bonuses to some things than to others seems arbitrary to me. Why can I get +2DV to blades but only +1DV to clubs? Why +3DV to unarmed (here again, it's of no use at all that there are more than 3 references to it!) but only +1DV to damage inflicted while grappling?
Makes no sense for me at all. As i said in some other thread already, just a list with benefits and how often you can take them, would be far better and streamlined.
