It had only been recently that Ash had learned how to speed her movements up with the method she had learned with a lot of effort, so it could be helpful in many ways, but there could have been a time when she never had it, and that could have cost her.
One of the main reasons why she would be severely lacking in a fight against a Balancer was the result of her lacking in combat or support-based techniques.
If another Balancer had mastered one or more of those techniques, then they would have a huge advantage over her in combat, even if she had been able to hone her combat skills against ordinary humans.
If they were able to finish their first chant, then that was when they would be at their most dangerous, and Ash would have had very little to counter them.
It was the same when it came to others who possessed an ability of some kind, and Spirits or Evil Spirits that would be less affected by the techniques she had learned so far.
