Well, I wouldn't call them underestimated. Bisky as we've seen is a Nen master and is very experienced regarding Nen and fighting. Although I'm too sure about Machi. Sure she is a PT member but we haven't really seen her other ability beside those "Nen threads". Remember the scene when Gon and Killua were held captive in that hotel? Just a bit more force, Killua would've seriously injured her even he just beginned to learn Nen. Killua in his Godspeed mode now will be able to easily defeat her...
