Ok, you know what: scaling is so messed up in this game.
b+2,1 > dash > 3 xx Trance > b+2,1 > dash > 2,1,2 xx EX Ground Burst (Final hit deals 4%)
b+2,1 > dash > 3 xx Trance > b+2,1 > dash > b+1,1 xx EX Ground Burst (Final hit deals 5%)
Conclusion: b+1,1 scales better than 2,1,2
b+3,1+2 > dash > 2,1,2 xx EX Ground Burst (Final hit deals 6%)
b+3,1+2 > dash > b+1,1 xx EX Ground Burst (Final hit deals 5%)
Conclusion: 2,1,2 scales better than b+1,1... wait, what?
Where am I going wrong here? This is making it really hard to tell which string is the better choice.
