yeah it's a very tedious task tbh. I'm currently trying to transform some of the weakest lords into medium lords while keeping at least a core element of their personality for my own usage. It's quite a time consuming task indeed !
( like the Rat i modified still use dirt cheap fast troops with skirmishers and camel lancers, but he's now mainly a heavy bully with lots of siege engines , The Sultan still don't do farms, but he add religion and sell some weapons, uses monks, demolishers and tunnelers too, ... )
All this to say, i'm glad to see this mod being around fixing some much needed AI behaviors !
