I recommend changing the AR of some songs from 8 to 9+ so they become more playable

no mod (NM) farm maps in the 300-400pp range that I played, not all of them are worth trying to get a full combo but they are a good foundation for building the required skills

HDDT farm in the range of about 300-400pp, there might be a few maps left worth 200. Not everything is worth the effort to full combo.
