This is my opinion, after looking through the forum/using search, I found one topic about being able to use orochimaru points on more pvp's, and i think, like intellegence, for every 20 or so _ you get 1 more pvp. This was brought up in another topic, but never answered, and never was there a request for how many oro kills/points you need. Also, I think at about 20 oro kills or so, this option should be available, not to newbies, but people who have worked hard to become strong.
Thanks for your time.
