These changes were meant to increase sizes of hordes and make them get larger at earlier game stages. So if you find it hard to go into cities now, it will get harder with these changes

I have been thinking about turning the horde repopulation up to 5 or 7 just to hopefully create some periods of "lull" if you stay in the same area. Current setting make base building a bit tricky and will probably run us out of ammunition soon
