The new system with unit allocation is unbalanced. It's impossible to defend against double the number of AI unique units (like Danyang and cavalry) with half your starting units. Some are able to defend better because they have enough land and production initially (like Yuan Shao), but to start with Liu Bei having nothing but 5 generals and 3 troops in the capital is like making bricks without straw (or as Liu Bei would say, making sandals without straw).
For example, starting as Yuan Shao in settler, you have 5 units in Ye and a huge army up north. If you start as Deity, not only do you lose ALL your units in Ye (leaving it vulnerable and unhappy), your army up north is reduced to 1/3 its previous size, but your little neighbor to the west has a stack of 5 cavalry and 6 archers!
I think you should not increase the AI's units, just decreasing the human's is enough of a challenge. Also, defenders like archers and crossbows should not be deleted.
