Just some random idea. Why not add something that lets us directly control our pets?
Also, maybe there could be purchasable pet upgrades. For example, adding new animations, or giving them autofire robot's ability.
And if you add the latter upgrade, as well as PRC, make it so we can "kill" other pet robots (but they respawn/get back up, of course.)
Also, PRC could tie into that one "Network" idea someone had.
Finally, since I'm talking about 'bots here, I just want to report that autofire robots can kill in non-pk areas. That definitely needs fixing.
