This was actually a Ver B2 change I believe, or maybe even B. They also made shield bunker cancels less useless/less beatable in general, so for many characters, the shield bunker is probably better than any bara they could do, and since the frame buffer is now 8 frames instead of 12, it's even less practical to use any bara except for 214, or 421 moves.
I think only Kouma really gains a lot by learning how to bara well. If you're using any other character, step up the rest of your game so that you get to the point where knowing how to bara DOES matter.
