Mugging parties on the Kroffburg road - can we just not?
Getting your feet under you to begin with is a bit of a challenge in POTM - which is reasonable, but there should be ways to work through it, otherwise you just put new players off.
Right now, putting a substantial amount of busywork in to run cargo delivery is a nice solid route to get some starting income, to get to know the geography a bit, and also to meet people on the trail.
If you put mugging parties out there, you essentially cut off that income stream and introductory travel for newbies entirely.
