This seems to be the case, and I'll probably start playing it as such, but do enemy armies naturally get more experience the longer into the game you get? I'm rather slow in advancing quests, and ended up consistently going against all rank 4-5 or higher armies in every battle, while my own armies have few units above 4 even though I've lost minimal squads. It makes quest battles extra difficult, because they're usually 3-4 ranks above the rest; do I need to speed things up, or is there something else going on here?

Please Help.
Thanks !

I didn't find the right solution from the internet.
