Hard disagree.

She's been on top of the mountain for nearly a year, and this is the one single fight Becky herself has actively seeked out, rather than simply retaliating. I think Becky wanting Asuka so bad that she puts her title on the line to get her revenge, and actually lose, is an infinitely more interesting direction to take. Kinda like HBK v Taker, now that I think about it.

It's been so long since Becky's been humbled - I think Asuka being her kryptonite (at least for a little while longer) would be great to keep crowds from turning on her and give her room to grow (or devolve) as a character. If Becky needs to look strong even in loss to Asuka, have Kairi be the cause of the loss.
