Hello there. I have few questions regarding the units size. Everybody says that DEI mod is made for extreme units size...what does it mean? What happens when we change it? Is there something special that armies do when its set to extreme? Is there anything they lose when its set lower?

Is it possible so change the units size during the game? I started the game with exreme but now i see that its to much for my pc especially in the late game where sometimes I fight battles like 2 armies against 2 or ever 3 armies :( I changed it in options but it the size is still extreme.

I would be very grateful for clarifying this to me :)
