The wilderness is pretty boring. You pick an option and just leave it running. But the affinity gain is pretty weak, and there really isn't a reason to try and get qi. The martial will is nice, but the only thing is does is let you survive a little bit long in the wilderness. Which means the only reason to go to the wilderness is for the imprints. Which have a single roll to be discovered with a relatively low chance.
That means the best thing to do is to go to the wilderness select any of the activites and wait for a decade or two. Then manually restart and do it again. Over and over. With no real variance between the different wilderness regions. Doing 45 dual element towns was already a lot, but at least they had marginally different narratives. The wildernesses is only distinguished by a few lines of description.
At least give us a way to increase the chance of finding something. As it is just not worth doing. Plus it seems to imply that there are ways to progress deeper, but once you go to a wilderness area you're stuck. You can't go back. You can't go to a different region. You can't even go from a mono region to a dual region. So unless you get the imprint its basically a wasted life.
