Ok, so there is no cooldown for the nation prospector. But there is no way I would do that more than once per day (or year?). Digging mission mats over q200 is a giant pain- not having region and material specialization :( About 60 minutes of effort (and exploding a few times) for essentially 250 sap crystals. But I guess I won't use those all in a day... but I don't really need the 60k dappers they gave, if I'm doing a mission for faction points it would be nice to just havemove points as dappers can be had easily.
