I'm sort of new to mania (been playing for 40 some days, have about 2000 pp) and this is my first post, but I really quickly noticed that the ranking system for mania needed to be changed somehow. The thing that bugged me the most is that 4k-8k are weighted the same, but 4k is much easier, so in my case like many others, all of my top scores for pp are from 4k songs. I could do really good in my standards on a 7k song, but not get any pp for it because I did a little better on the 4k songs, even though they are easier. For auto-converts, most of them get low difficulty ratings anyways, and you can easily get more pp from mania charts than you could from auto-converts. IMO, I wouldn't take auto-converts out from giving you pp, because if you're good at mania, you will get more pp from the mania songs anyways. That's just my opinion though, and I don't really know how far you can go, farming standard songs. If there were more ranked mania charts than there are currently available though, I would probably be more for disabling pp for auto-converts. There are also some songs that are considered way too high in difficulty (i.e. Utakata) that give you way too many pp.
