I did, yesterday 

Okay everyone, so I got the easier ai done. I present to you, the one and only (AFAIK) EasyAI!!! EasyAI has the following changes (read the README for more details): - EasyAI never builds arsenals or fortresses. - EasyAI never trains heroes or siege machines (though it can use captured ones) - EasyAI sends smaller attacks, around half the size of Petra's. - EasyAI takes much longer to phase up. - EasyAI trains less workers. - EasyAI builds less fields. I tested EasyAI against Petra, and Petra beats it consistently and severely. Let me know what you think of it.  This is only version one, I might make some more changes in the future (EasyAI never betrays the player, EasyAI never captures buildings, etc.), but here it is:  EasyAI.zip

Just tell me what is imbalanced…

so,let me get this clear: You think there is nothing particularly problematic with the balance in R28?
