Weeeeeeeeeeell, I think it needs way more to be discussed since many people are absolutely against this system but also it has some logic system behind of it. Specially because things like https://osu.ppy.sh/s/42854 and https://osu.ppy.sh/s/56847 can easily be mapped as full Mapset.
I find that the BPM should affect as criteria if a Map is worth to go as Approval - as popner suggested Talent Shredder with a BPM of 280 - and that the Song lenght should be more a secondary point if we do allow someone go with its Map to Approval. Also of course we shouldn't forget the point if a Song is pretty complex and hard to map (to be honest I really do not know any songs which falls under that. I just name this because there are people out which has a different sight of this.)
