So right now, I'm FRCing (or at least trying to) by pressing square, X and circle simultaneously, but this is such a pain because I got to shift my hand a little bit (to perform FRC and to return to its normal stance) and my thumb sometimes touches triangle as well so even if I hit the FRC I just end up doing Slash which defeats the purpose of FRCing in the first place.
So is there any easier way to FRC or is it just practice practice practice?
