I did some difficulty reratings lately. Note that if you have finished any of these maps, your points will be altered.
4s: Insane 1* -> Brutal 5*
4u: Insane 2* -> Insane 3*
Aimlicious: Insane 4* -> Insane 3*
Barren: Brutal 2* -> Brutal 1*
Jajka: DDmaX 5* -> DDmaX 4*
Stop Over 2.0: Solo 2* -> Solo 3*
Feel free to suggest reratings either to me, in #general or in the map's testing channel if it was released recently. (edited)
