Hm, I think it could go either way.

I'm just being exceptionally cautious before I lock myself into a role.

The way perks(?) went though, I think people just kind of pick whatever and diversify, so maybe it doesn't matter.

Thing is, while we could have a lot more people Protecting, we haven't got any clues yet how Stalkers pick their targets.
We have only needed to do one Rescue.
We could Forge, but have no materials and no blueprints really.
Investigations are fine but take twice as long to do as just an interview -- and don't necessarily turn up anything conclusive. We've got so many unmet suspects, can we spend that kind of time shooting aimlessly?
Clairvoyance could be useful, but we more or less know what we're working with... though maybe it'd help us find more skin patches, things like that?

There are still so many places to search and Pokemon to interview. Heck, like 4 cycles ago a bunch of people took a perk that's exclusively for Scavenging, and which we can't even do 'cause nobody'll talk to the Poke' who tells us about it! But, I think that just means everybody is going down their own little diglett holes -- including me.
