Unarmed / Swarm Strike + Malignant Mist?

[rabidradioactiveraccoons]

Rereading the description Malignant Mist, I've noticed it lacks what seems to be an obvious synergy with the Sheath Array. As is stands, it is purely a reactive defense mechanism, but unarmed strikes (Swarm Strike in particular) and/or natural weapons seem like they should be vectors for the infection. Sheath Array is already lacking in Faculty support and offensive options, expanding its use with Infestation seems like a step towards remedying that problem.

Though, to be fair, if you're using Swarm Strike, you're also going to be attacked more often, triggering Malignant Mist.

Still feels like a missed opportunity to give the Sheath Array better Faculty support and a missed opportunity to let the Nanocyte punch parasitic nanites into people.
