True. Could be beneficial in some way, but drone does its own job very well. Well, it doesn`t poop in the middle of the street out of fear when a surprising horde appears, but..us, humans have always had animal companions around us, domesticated and such, through our own evolution irl.
In apocalypse would be indeed very cool feeling to have one, no doubt about that. It is easy to speak about it, but not so easy to implement in such a complicated environment as in this game.
Fingers crossed for a one or more, in 7 ways to die 2 !
