I'm glad I found this thread. I downloaded the K-mod recently and am playing a 2 solo humans vs 8 AIs game.
I am Alexander of India and have had no archer rush. The first thing I noticed early on was DeGaulle of Byzantine demanded one of my Clams (my capitol had 2). I only had 3 warriors at that point, so I said yes. I researched Archery and spammed out a few to improve my unit ratio. After I built a couple of cities and hooked up my copper, he demanded a Fish off me (I had 2). I said No, but asked to trade it for 1 of his Corn and he said yes.
I have kept 1 axe, 1 spear 1 archer on his borders and he hasn't attacked me.
So far the K-mod seems pretty decent.
I think, it is great that people think that PRO is now a more valuable trait. It is also a bit comical to hear about archer rushes and pillaging as a problem. Since, I have played Always War games for the early fighting. I remember someone earlier saying that archer rushed by us were possible, under the right circumstances. It's cool that the AI sees this too. I guess the lesson is; Don't leave yourself too weak and you shouldn't get rushed.
Good Luck with this game. It looks like you are doing well.
In my game, I guess I'll find out just how hard Monarch K-mod has become.
