The setup i use is a tad different then most:
Tap jump on
A: Special attacks
B: regular attacks
Y: regular attacks
There's several reasons for this, the first is that i used to main lucas, and felt that zap jumping was very important (For those who dont know, zap jumping is basically jumping then using lucas' forward B in a specific timing, giving a huge upwards boost)
There's 3 methods to do it, one is b-sticking, second is clawing, and the third is doing some attack priority stuff, which i REALLY dont wanna go into here.
I decided to change my configuration for this, eventually it just became natural to me to ues this.
I'm still thinking of any holes my controller setup may have. One of the bigger ones seems to be the fact that i need to pass several buttons to reach the C-stick, though i'm not sure that's that big of a problem, but I dont see any problems with it, so if anyone can point something out, i'd be happy to figure them out, thanks.
