To be honest i'd be happy if PPV2 took some influence from osu!tp's way of calucating difficulty and giving points based on that. The whole problem with PPV1 is that difficulty wasn't relevant. A ranking system that gives out points based on map popularity and other factors that aren't relevant to the actual difficulty of the beatmap is not how you calculate the rank of a player. It was very inaccurate for calculating the actual skill of a player.
