Most of this was, "Yeah, okay. I can see that. Why not?"
But then you hit Scavengers and that was a brainstorm. What a great insight that allows connecting currently homeless toons like Ugnaught into something that invites new mechanics and gives them a home for ... something. An event, a raid, whatever. Just a brilliant little characterization insight that CG should definitely take seriously.
To be clear, this shouldn't make them into a new powerful faction. But giving them synergy , making them part of an ecosystem -- especially tying in with Scav Rey -- could/would make them an interesting and fun faction.
Very well done on this one.
