I have noticed that the scoring system in mania as it is now doesn't seem to work properly. I have played many maps and got higher accuracy and combo, but lower score than a previous attempt. I don't understand why rainbow 300's give considerably more score than a better combo or accuracy. If this is the direction standard is going, I don't like the change. To my understanding the reason the scoring in mania is odd is that it is score V2 (higher combo means you can lose more points for anything under a rainbow 300). Imo the scoring should take combo into account for a multiplier (of some description) and then award points based on the accuracy of the hit instead of calculating a theoretical maximum and then giving you a score penalty for anything which is not a perfect hit.
Edit: The scoring system is just strange compared to standard and doesn't make sense if you use the same criteria for improvement as standard. (In mania it seems rainbow 300s are more of an indication of skill than accuracy or combo like in standard).
