ps : to give an idea of the difference I've made a test using the easier to find sites mod (all mages sites discovered) + another, and giving to 20 land nations 9 provinces at start, with 45% site frequency

- with vanilla (no mod changing frequency) 7 nations got one mage site, two nations got 2, one got 4

- with the frequent mages sites mod one nation got 4 mages sites, 6 nations got 3 mages sites, 4 nations got 2, 7 nations got one (two had zero)

- with the rare mages sites mod only 4 nations got one
