I'd check with Rune first. To say what you've identified at this stage basically amounts to a sub-role claim so I'm not sure we'd be allowed to do it en masse.
Rune, what do you say?
Yeah, this counts as a mass claim.
Also, I've come to realise matchers are kind of OPd.
I'll nerf them so that if the get 0 results or 1 result it will come up with 0-1 instead of the actual number. (Otherwise they're almost seers especially if it's a mason/villager.)
I've matured and I don't lie now, really. C'mon trust me.
