I understand your statement, but I don't totally agree. The Akatsuki members would have at least known each other's abilities and what they can do. Just because it took a lot of lives for US, the readers, to find out about their abilities doesn't mean that they don't know about each others.
Yeah, but if the Akatsuki members knew each other's abilities thoroughly, then why would it be so difficult for akatsuki-Orochimaru to defeat his previous partner Itachi?
