Free Step Dodge

I think it's optional since you still gain 90-100+ points of damage, though recommend it and preferred to learn it anyway to just get it out the way. The electrics usually provide 15-40 points of missing damage which is still damage and a step closer to kill them. I don't see why not on learning it.

I'm trying but, it's just hard for me. I even watched your vid on how to do it but it's still hard.

Pretend it's like a Tekken wavedash into EWGF, I.e. 6523P input. Raidou's version is more lenient; it's not a JF but you can't quite mash it out.

Actually if players play via pad (especially dualshock) they only need to input 6~3P. Basically 6[3P]. The dualshock doesn't have a proper diagonal input and forced to input 2 and 6 just to get 3, so what you are doing is taking advantage of the actual configuration of the controller itself.
