It seems to me that the drone can already fall neatly into the established system. If you perk into Robotics Inventor, your drone(s) would gain the advantages of:
- being able to be crafted in the first place
- better craft quality
- better damage
- better fire rate
- better clip size
- better active range
- better active robots at once
And as you level up Intellect itself, your headshot damage and dismember chance with drones increases. This is all stuff that would happen just from extending the existing design. If you have all that, while someone not perked into Intellect doesn't, is that not appealing to Intellect builds? Is that somehow putting Intellect builds at a disadvantage, when it's all the same kinds of stats that other attributes/perks affect?
On the carrying capacity... well it may offer something cool to everyone on that front. But on the other hand I'll happily use, say, explosives without perking into Perception, because explosives do some uniquely cool things that no other weapon class does.
