Why?
Missy is a Shaker; she can detect people in her field when she extends it IIRC.
There is no need for her to expend a Charm slot on MSD.
Plus, familiars share senses with their primaries anyway.
She doesn't actually detect people, she only feels the added load on her field the more creatures are in it, and we know it doesn't differentiate between Person and Bug, given that a sufficiently concentrated mass of bugs makes her powers fizz.
But the drones do a number of things here:
-Remote social interface. Any of our socially oriented Exalts will find it extremely useful with conversing with or coordinating people remotely. Think what we can do with our bugs, except it's got a MUCH greater range and isn't as creepy.
-Remote sensor with all that can be packed into Alchemical Bullshit senses, including the possibility of getting Unsurpassed (Sense) Discipline effects loaded on every single drone.
-Telepathic, it allows for communications without external leakage, with anyone who has the drone nearby.
-Unlike our swarm however, the drones are part of her body, meaning it potentially has the capacity to act as a range extender for her power without having to cover the entire intervening distance with her power(and pay the effort surcharge for number of units in the area). I THINK this is the 'fun stuff' surprise we missed out on, considering what it might do for our SoPA if we had it.
-Coupled to IEU, she can then use the drones to provide battlefield control support for any individual on site team within the city.
-[j/k] Rocket punch option
Overall, a useful addition, and one she should qualify for easily, while also not being very costly. A suite of social charms, a suite of sensory charms, a suite of mass combat charms and Alchemical Combat Basics works fairly well.
Transcendent Multimodal Artifact Matrix makes combat charms a relatively low priority due to packing a good armory(there's very little to be said for combat ability once you throw in a daiklave and artifact armor), and her own power makes hard defenses less vital, as long as she can sense an attack coming, she can warp space to not be there.
The key is being aware of anything she can't tank incoming, which is where sensory charms come in. Secondary Sensory Upgrades with Mobile Sensory Drone is extremely powerful when you have an ability like that.
Take 20 charms:
-Fourth Charisma Augmentation x2
-First Wits Augmentation
-Fourth Stamina Augmentation
-Fourth Perception Augmentation
-Tunnel-Fighting Tactical Omnibus Implant
-Omnipresent Guardian Directive
-Patrotism-Provoking Display
-Motivational Vocoder
-Radiant Iconography Array
-Pattern Facilitation Module
-Programmed Catechism Rebuttal
-Integrated Artifact Transmogrifier
-Husk-Sculpting Apparatus
-Transcendent Multimodal Artifact Matrix
-Industrial Survival Frame
-Anticipatory Simulation Processor
-Mobile Sensory Drone
-Optical Enhancement
-Secondary Sensory Upgrades
I expect both Missy and Armsmaster would come with TMAM.
Missy in particular, because TMAM+Essence Pulse cannon makes her a Blaster 5; add an artifact with an Elemental Lens and she becomes a Blaster 7-8.
Then load a suit of superheavy plate in there as well.
Colin OTOH would probably load his TMAM with whatever he tinkered up, starting with his halberd and armsdriver.
And if he got an Essence cannon, it would probably go in his eyes or on a shoulder mount as an auxiliary weapon.
Remember with All The Submodules version, it comes with an array of useful robot pets as well as a full armory of armor and weapons, which the PRT cannot remove(due to being body parts)!
