Alright I got a problem with all the gates being of S-rank calibur if anything the last gate should be of S-Rank. If all the gates are of S-Rank its impossible for someone to even learn all eight gates. The maximum S-Rank moves a Kage/Akatsuki leader can learn is 4 so they wouldn't even be capable of learning all eight gates. I say first gate - B rank, second - B-Rank, third B rank , fourth B or A - rank, the next two A rank and finally the last gate S-rank. I think this would be more fair, but this is just my suggestion.
