also, i'll be narcissistic for a moment and bring this into play: i'm arguably one of the strongest players with regards to accuracy on 4K, and i'm not fully opposed to a system that has a bit more of a combo-emphasis. I'm not advocating a situation where someone with a 92% FC beats a 99% with a miss, but I do feel like there are certain situations where combo should hold a bit more relevance and it simply doesn't in the current score system.
With then new changes, those who have good LN abilities also get rewarded, which I think is great. AiAe is a good example of where I think Score V2 should make a positive impact -- there are numerous players who have substantial combos and AiAe [SHD] is not exactly something that anyone will be renowned for their fantastic accuracy on (unless they're cheating, of course). Players who manage to break into four digits of combo on that should be rewarded a bit more than players like myself, who struggle just to get far into the three digits on a good run.
Oboro is also probably another ranked map that could see a good shake-up with the new LN mechanics.
I do think that the formula is a bit on the extreme side at the moment and I know that a few people have ideas on how to make it a -bit- better while still having that combo orientation.
