Using the mouse is pretty hard, I mostly rely on arc and curve tools to do the heavy lifting,
Also, I keep jumping back and forth, but do you want your character part of the buddy system or the bounty system?
You seem uncomfortable with the idea of the defeat animation, and I do have to admit I am uncomfortable with putting peers into any enemy systems.
The Bounty System: Is a system where you hunt down a creature by following it to the planet it is on and then get a reward.
The Buddy System: Is where you do something special and they follow you into combat and assist you.
