[@jensoman] I don't quite get this part of your post. 
The three pirates with the flint-lock pistols were hit hard by Asus's hornet ball technique, sending them flying throughout the bar like ragdolls. They were knocked out instantly. The ball ended up striking the front door of the bar in the process, smashing hard into the door and creating a large crack within. None the less, however, the path to the door was now clear, allowing the people in the bar to escape.

While Asus can control them and thus make them act unnatural his hornets are still just hornets and the most his hornetball could do is scatter and sting it's targets several times while maybe blinding them. The ball thing is more an easy way to send a large group of hornets in a single without the risks to them that would occur if they descended on their target like a cloud ie single hornets getting killed but with the risk that the entire group gets killed in one attack.
