Ok so I know the garrison cap is 20 and that's most likely a vanilla game limitation but is there anyway it can be raised? I just realized it and now it makes no sense just trying to make buildings with good garrisons if it is just going to cap and I will have wasted units that will never be able to defend. Also on level 3+ cities I am not being given any defensive siege artillery which I'm guessing is due to the garrison cap as well. It just sucks having artillery in a city and not even being able to use it in a battle, anyway to workaround this and adjust the garrison cap manually? I have tried this with Sparta and Rome and am not being given defensive artillery so I believe it is a global faction issue.
