These are fairly minor, but I figured they were worth listing. There's a few weird things listed in the various backgrounds which seem really out of place.
Firstly, why do Administratum characters start with Quick Draw? It seems like a really nonsensical thing to give them, Adepts and the like aren't exactly known for their nimbleness, so starting them off on the Mobility tree is just... odd.
Similarly, Mechanicus characters have an odd entry in the form of starting with Athletics as a skill. I don't really understand this at all, surely Rememberance or Medicae would fit the spot better?
The Ministorum background also has some odd features. For some reason, they start with a utility servo skull. I can't imagine priests have a lot of use for what amounts to a hovering toolbox. If they're going to get a servo-skull, give them one with a laud hailer, makes much more sense. Also, Ministorum characters start with mesh armour, which just seems odd. Shouldn't it be robes?
