General rules for online games.

That's a rather weak argument, and it's not up for discussion. I personally liked Dyrman's idea. What's the point of weeks if the main bonus from them is lost? And when generating only non-native weeks, all other bonuses remain where they were (except for the double increase, but it should also be imbalanced according to your logic. For example, if humans have an increased monk growth rate, their Axel can train more knights, which is also unpleasant, although not as much as having many copies of a creature, like Karl does). Both the Path of War and the Astrologer (not only does the world not converge on weeks of creatures, but you could then allow joining, which would be very pleasant, otherwise the perk just sits idle, and you can order a week of genies, for example, which is a much more beautiful "tactical trick" than simply choosing a week of your own creatures from the Astrologer for a double increase).
