Just a few notes here:
(a) There are NO supported minimods. By definition. Everything EB supports is released via the EB server (click on a 3rd party mirror and you will make a slight detour on our server regardless).
(b) CTD's do not and could not multiply exponentially. Do the math.
(c) The difference in AI is a rather subjective experience: some people here for instance improved much better naval activity using BI others claim that the naval activity now resembles the AI for land operations. With ALX the main feature appears to be [note I use plain RTW, but have read others reporting it] the fact that the AI actually retrains/merges troops.
