Again, her semblance is effectively useless if she can't hit Neo.

Imagine this, Ken is about to perform a Shoryu Reppa, and that uses up a lot of meter. However, it whiffs.

That's a HUGE waste of meter.

Yang is doing the same, if she pulls out her Semblance and it misses, then she just wasted what could be used as a finishing attack. So until she knows she can hit Neo, then why use up her semblance right away?
