Yeah, like Hatman said, in the end it's your choice.

But I think it would be cool if you had something like Rumble balls, like three or so.

They could make your hornets stronger, up to the point where your hornets could withstand blunt attacks and projectiles that don't pierce. As such, they would not get crushed if you were to use them to make like, a giant fist of hornets to punch something.

The effects of something like a Rumble Ball might only last for a certain amount of minutes, like, say 5 or 10 minutes maybe.

That's just my personal input on the matter, but let's keep brain storming until we can come up with some ideas that you might like :P
