- In practice, popularity of songs in different genre differs significantly, enlarging the problem that come rare choices of song recieves less caring (2kd-system may cover this one). If this is simply a numerical requirement, mappers will just find everyone and tell them "hey give me a pop-level (pop-level sounds lol), just like people asking others "hey star my map" back to the days that the first star is free. Then popularity level is even easier to be abused comparing with current system.
- Mod-level's problem: In practice some modder tends to star the map after certain rechecks --- starring the map shound't be linked with (the a certain modder's) first mod.
For me it's like # of mods = count by myself reading others' comments or problems; popularity = number of posts/views is pretty good estimating already, and imo popularity of a mapset is largely depending on the song while the quality of map is only has a boosting effect in general, which doesn't really help much about map's quality.
Icy speaks most of my idea already, and I agree that
I can't really see a strong need in upgrading a system.and maybe I don't think it's not really "unfair" because the costly and limited stars pushes us to save for better maps that deserve stars while sacrificing the rest of the map.
