I think you DO choose the ability, but it depends on whether or not it falls into your original type.

If it's not Isuzu-chan Mii~
You obviously choose the ability.
My point was, if you choose your ability to be "I purge other people's nen" then you have an ability that has almost no combat applications.
Given that most Hunters choose their abilities for fighting, it's not at all surprising to me that Nen purging is rare.
