So the group have gotten hold of R5-K3 from Escape from Mos Shuuta, as a joining member (ally). That's fine, I thought, as it's only a grumpy R5, and they need a bit of mechanics/engineering help.
But then I noticed the book itself doesn't stat this droid up. I saw that the R5's were the cheapest R series droid. So I was wondering, how far do you think I should go in downgrading this little fella from the regular astromech? And how? They did after all get him free, as a stow away (troublemaker).
Even if it's a case of them being able to spend credits on upgrading it later.
