I don't see why people have such trouble opening up with BRC. Its not about the first hit but after that. F1 is a great poke, f11 is high with great range to low with great range. Cancel f1 with flips of death and destruction and that's where the mixups are. Same with b1~low grab. It cancels the 2nd hit that's an overhead for the low that MBs into full combo restand.
You play footsies with f1 and d4. Not everyone has 50/50s into 40%. Focus on 17% here, 36% there. It all adds up.
The only problem I see with BRC is how he gets in, not opening up.
And the flips corner carry really well, so does lunge kick.
