#2 Unpinned or submitted on television
Though she's no longer undefeated, Asuka has yet to be pinned or submitted on television. This ensures that her pay per view losses feel bigger and more important, even if some of them have been astoundingly stupid. You know which ones those are.
Those pay per view losses were what dented Asuka's aura, her television strength ensured that she never looked too weak for too long. Her biggest problem was the perception that there was a glass ceiling she couldn't find a way to break through.
Though Asuka wasn't in a good spot until late in the year, it's worth remembering that the white hot Becky Lynch was in an even worse spot until her summer renaissance. In that regard, Asuka's TV strength ensured she could be built back up again credibly and smoothly. It's paid off as 2018 rapidly comes to a close.
