The pull system is jacked up to say the least, I'm over 1100 seals into GNW treasure and still no super rare aka Naruto Kurama mode or Madera. I posted a similar post in another section and the replies were informative as well as daunting. Plus in all those pull I'm still one rare short of finishing the collection! I hate to say but the CN version/servers have better treasures and the functions are virtually the same as on the US server.
