I assume you don't know this but this server is not the original server. The server that is the oldest is in China and it has a lot more content and ninjas (including Madara) than we do. They continue to add more content and ninjas. It is just a matter of time as to when we get the content and ninjas from their server.

I want drunken Rock Lee the one who fought against Kimimaro

Madara and naruto kurama will be the two super rares in gnw treasure. You'll get one of them around every 1000 seal scrolls used. The eta for it to appear is around 6-9 months since now, but exactly like happens with ay 3rd raikage now he very likely will be available earlier as a whale only toy 1-2 months before.
