I am a 6 digit player (210k) and I can fc some 3* maps and occasionally 4* (at most 4.7* or about that range I think) maps. But I haven't tried to play a 5* map. Should I try playing one?
You probably won't be improving much by playing 5 star maps since they are way to hard for your current skill level, but you obviously can just try and decide by yourself
