Another bug. Druzhina affects the units in a bad way... infantry shots don't count anymore, they have to attack several times for 1 hit. I did the test with 20 E Kamayuks vs 20 Cavaliers (the result is obvious for all civs but for Slavs) and I was shocked - at some point 7 Kamayuks were continuously attacking 1 Cavalier and he refused to die. Slavic Kamayuks act worse than Magyar ones for example even though they have the same stats. I also seen this problem on pikemen and swordsmen, so I think there is something wrong with Druzhina tech.
