Well we don’t know everything about it yet. It’s most likely that they added something to the regular RCs or took something away from the YRCs. Most likely adjusting the amount of timeslow.
About the FRCs and RC debate. I believe they will be like this…
For certain character’s moves in +R and AC and the such, doing an FRC on a special attack that actually hits the opponent can either cause an FRC or an RC to happen, whether you miss the timing on the FRC or not.
Take for instance Johnny: His FRC point on the Killer Joker is pretty strict, and if you mess up, then you get an RC which takes half your meter, or nothing will happen (not having 50% tension) and you will be left open for counter attack.
It seems to me that they took the unfairness of certain FRCs and just made them global for all the characters, so that some will not have “free try” FRCs and others have “gamble FRCs.”
tl:dr. If you mess up the FRC and don’t have 50% tension, nothing will happen/ you get punished, else you will get an RC.
Considering all these characters are being created from the ground up (not reusing old sprites/etc.) it is quite disappointing that while for some they have given exciting new looks, for others they have just kept them the same.
I wish they would either go all in with the redesigns or don’t give anybody redesigns. It seems like preferential treatment or something to the ones who did get an update.
