Well for one, Digiquo, the effectiveness of how to balance the actions of the weapon is entirely irrelevant to the validity of how it works.

I'd suggest that you just accept the information being presented. Hell, it's on this wiki already.

"In a new Famitsu Magazine scan, a new Weapon Class is revealed (操虫棍) "Operating Insect Rod". This double-ended staff is capable of quick fluid attacks like the Long Sword, but it also is capable of summoning a large Neopteron that will drain energy from monsters to boost the Hunter (in terms of attack, health, speed or defense)."

Famitsu should be good enough of a source for you. If not, I don't know how to help you. Just to pump more information into you, because apparently that's what you crave, have these in-game screenshots of the weapon in action.
