Just stop complaining Emaal, any automated system like this will be about farming and you can't do anything about it. You can be a god player, be able to clear Airman on DT (I know it's impossible), but that's not worth a thing. All you have to do is go farm top scores to raise your ???. This is in the end just another farmi based ranking system, not much like the last one but in the end it is not a very different thing.
That's what I think, guess we should wait for peppy to finish it and see how it works out, my suggestion again:
Ignore FL scores (except it's something like DT+FL or HR+FL), give ridiculously high values to top scores on popular maps where many top players appear, make Hidden scores worth shit, make normal no-mod scores on maps where there is a lot of mod playing worth shit too, HR should be worth tons more than Hidden, DT way more than HR, very high ranks (#10+ on popular maps) should be worth a ton. like really, high ranks on stuff like
http://osu.ppy.sh/b/83968 or
http://osu.ppy.sh/b/80515 should be worth gold. Of course getting #1 on FL+HD should be worth nothing, remember if you want to make a ranking system not based on grinding, you first got to make grinding mods worth crap, DT+HD is obviously harder than DT only, not because of grinding but because of map readability and note-snapping, same on HR, but HD alone or FL alone (same FL+HD) should be worth almost nothing, like yeah go get some fame having #1, but don't get into the ranks higher than other guys that actually got the skill to DT that thing in a few plays when it took you hundreds to FL it (and yet you are completely incapable of doing DT).
