I just can't. This guy is giving these hornets sentience and abilities akin to summons, without actually calling them summons. It's like he wants an Aburame without having the drawbacks of the Aburame. He wants to circumvent nature without a reason why. I was just giving him a head's up, "Hey, my character can do this, just letting you know." 

If bugs can keep genjutsu at bay, then my character's pheromones can keep his hornets at bay. Same concept. My character can't CONTROL nature, only influence it.

You have your warning. I'm not pulling any punches, nor am I compromising my character.
