I was searching the files inside ____edain_maps.big, but I don't think I found anything related to this in Edain's skirmishaidata.ini or "ki [faction].map" files. Anyway, I wanted to ask which files determine whether the AI sends its starting units on a rush or not. I know at least Gondor, Lothlorien and Mordor rush with their starting units, but Isengard never does.
It's really annoying on AI vs. AI style matches, especially 3v3 and 4v4, where Gondor and Lothlorien double-team an enemy AI (who has no forces defending since he's also rushing someone) and take the base out in less than 2 minutes with their starting units.
I'd like to play around with the AI behavior files, to make the AI units go after settlements and creeps, rather than enemy bases, during the first 5 minutes or so. I just don't know which files contain the AI scripts. An alternative fix for this behavior would be to give the Citadel some arrows to defend itself, so you'll need a bigger force than 2 battalions of basic swordmen to take down the Citadel.
