i dont know why you focus so much on army vs army, that part is still not improved enough
anyway the counter to archers as usual is magic (or other archers)
you cant expect a archer to not be able to kite warriors
Good point, but I am always hopeful that the AI will get to the point where it trains a good army. I have to think about balance with that in mind. The enemy currently is considered doing well if they ever put two units together and none of them are pioneers or scouts. The correct counters to archers should be other archers, cavalry, magic, advanced armor.
Let's take a look at the .982 armies on hard difficulty at the midgame:
The AI never builds strong archers. They never use leather. They don't have the traits that make archery deadly. (Precision, Fast, Muscle)
The AI never trains light cavalry with the intent to smash archers. They always seem to target light infantry first. They use weapons that weight them down too much to get the first strike.
The AI never uses anything other than Obscuring Fog to counter ranged attacks. Mages are so incredibly rare to see in an AI army and they don't counter enemy units as well as they should. Most of the time they cast Burning Blade and then get hit by 100 arrows.
The AI does not manage an elite team with armor upgraded to chainmail. It doesn't build a new team of the best armored units and put them all together. When they do have armored units, archers can just avoid them and go after the light ones. Then the chainmail units are outnumbered and ready to be slaughtered.
Because the AI does not use these counters well and does not manage a strong army, we are able to fight with only one army and defeat many. Don't get me wrong, the AI is doing alot better in the latest patch, but I am still reigning supreme due to better management and tactics. The AI does not even fill each army to its maximum logistics point, leaving me with more units in each battle. I think the major problem is that the AI is set up to fight the world, but unable to fight another fully trained army. Once war is declared, all units need to regroup and maximize their power. There are alot of times the AI could be playing a better strategic game to make up for its problems in tactical.
