As it has been pointed out by Taro Malkovich, is a pretty /-effective unit with items. I added items to attributes calculator and militia is the most effective indeed. So I added militia to the offense calculator as well. On top of that I also added marksmans to defense preset.
Fixed more bugs:
Building levels in offense calculator were not updated properly
Natarian troops in attacks incorrectly considered as infantry
Number of chiefs reset in shared link to conquering calculator state
Fixed several bugs on various pages, thanks everyone for reporting them.
