As a player, my personal satisfaction comes from playing different diffs from a skillset,because even with the same star rating, two extras can have significant difference in play, which i feel should not dissappear from a set.
I see the spread lately between easy and ultra hard maps, but I feel like mapping easier songs has a lack of options to choose from, which is why we see more harder maps maybe?
As for my opinion, I want to appriciate every style of extra difficulties mapped by various talented mappers.
