Most of the region activities are fine, but I think the "only person per activity" is going to break down in real gaming. As soon as the party is out of supplies, of course everyone is going to "hunt and gather" and would be pretty peeved if the DM is like....only one of you can gather. That just doesn't make sense. At the very least, include the help rule here, allow for one person to do the thing, another to give them advantage on the check. I can definitely see a lot of players who don't know exactly what to do would want to help another person. Better yet, just allow everyone to do it, and pile on expertise die for each person. Its technically less efficient than if everyone did different stuff, but hey if that's what people want to do, why not let them.
Agreed--
especially when combined with the idea that you can only do one activity per Region, no matter how big a region is. Help actions make a
lot of sense. Although I'd limit it to a single advantage (or bonus expertise die) as per 05e rather than let lots of people help at once.
I imagine some of the limitation is so you don't have people spamming Chronicle or Pray in order to give people bonuses on the other rolls. What might be useful is giving a minimum time frame for each action. You should be able to Hunt & Gather, Harvest, Track, etc. at least every few days (perhaps roll a d4), depending on the region. But something like Chronicle, Entertain, or Pray might require a week between uses (you're gathering info during that week, coming up with a new tale or song, or engaging in normal prayers without expectation of personal attention). And things like Busk or Rob could be daily but depending on the population of the area--and how willing you are to attract the attention of the guards, patrol, or more powerful group of adventurers.
I think it would also be nice to have some guidelines as to how big a region actually is. If LU is expecting a region to be only require a few days of travel each, then yeah, OK, I can see limiting it to a single roll. But it's likely that a region would actually be weeks of travel, in which case the multiple rolls would be useful.
OTOH, it also looks like LU is expecting that you're bringing along your hirelings to do some of the tasks, leaving the PCs to do the more interesting ones.
