No, just no. It's not that all Nen types you emission, it's just that many of the characters '''hatsu's use emission. '''It's not some Law of Nen that all Nen types must implement emission. More over; not all emitters use manipulation, not all transmuters use emission, and most definitely not all enhancers use emission! Razor was not manipulating the dodgeball, he was emitting his aura and throwing it; it was completely out of his control. Killua did not emit his electricity; all of his electric attacks connected to his body in someway(the same can be said for genthru). You're explanation for specialization was just straight up speculation; Binolt was by no means manipulating the universe or emitting nen when he tasted Bisky's hair. I think it's possible that conjurers use emission in a sense, it has been stated that conjured objects hold a substantial amount of Nen, but this may not always be the case. Also, it has been stated before that conjurers materialize their imaginations and create real, physical objects; not just transmute their emitted nen and add a "conjurer's touch" as you so called it. And finally enhancers; it's just a straight up no, they don't always use emission. They don't need to separate their aura from their body to channel it into their attacks, it's not what Uvo does with Big Bang Impact and it's not what Gon does with Jajanken Rock. If the "motion of aura" classifies the emission of aura, that would mean that advanced Nen techniques such as Shu and Ko use emission as well, which clearly isn't the case. So in summary:

Not All  Nen types use  Emission.
