Jaxy keeps warning us about this fact as if that would be a side effect we would not like. I for one would welcome lower populations of some species. I would rather run into a variety of species rather than the same old species all the time.
The first thing that comes to mind are predators. Many maps contain species of predators that feel overpopulated. Lowering them for backfills makes sense.
From what I've seen, the mechanics of the Snow Leppards has only received positive reactions from the community. What if each map had at least one species that were similar?
Below is at least one backfill for each of the older maps that could use one and at least one species that I believe could handle a decrease to make way for the backfills. (Don't get too caught up on my suggestions. This is just for proof of concept purposes)
