According to several others ITT MasterMO already did that.
Of course they are really mostly embittered because they were beat.
MasterMO pointed out that Jackpot users probably hit adjacent notes as well, so are they exploiters? To not break jackpot and effectively swap lanes for white notes and flame notes you would have to in many places. I discovered this accidentally, and afterwards I did it intentionally to hit adjacent flame notes, but I never put it together to do it as he described. He leveled the playing field, you all have the power, if you possess an equal amount of skill and don't miss you can do it as well.
I also discovered that Synchrony allowed you to do the same thing although the window sems much smaller, and the only reason I found that was dead space at the beginning or end of the songs honing my fast lane switching.
When my old slow ass lets a note slide by in RB3 but I get it just before it is too late, and consciously make that effort is that an exploit?
He is using a mechanic that is working as intended and being treated pretty poorly by a lot of people that tbqh have no reason to do so.
