My reoccurring concerns and applause for AI have consistently been the following:
1: Rather foolish or completely suicidal Allied placement and/or movement of transports while under heavy pressure. The poor/suicidal choices seem to escalate the more AI struggles. (The worst I've seen was in Pact of Steel China added WWII V3 where AI placed 4 undefended transports in range of an enemy sub having no chance of being neutralized before the sub could attack (and no apparent better option for the sub or forseen means of defense to arrive before the sub could attack).
2: in some maps, poor analytical choices in regards to how much or if at all to repair an industrial complex. I've mostly not kept track of which maps/versions apply to repair decision quality (however the map Pact of Steel China added WWII V3 seemed to make decent decisions regarding repair or lack of repair of an industrial complex [unlike most other maps] since they often just repair max damage despite the repair being either futile or a poor decision).
The poor placement/use of transports is by far #1 crippling the AI. I've noticed this issue often arises when France/Western Europe are well defended, Algeria isn't a good option and the allies will send undefended transports to attack Norway or other northern territories. I haven't read this whole thread and offer apology if this post is redundant as well as my lack of details regarding other maps. I play alot of various maps vs AI and have noticed these general patterns in various maps though have finally noticed a control group where more extreme aspects of both issues (good and bad) can be found in this single game attached (the map being Pact of Steel V3 China added) and hope the observation helps to either embrace and/or correct any scripts and apply changes to maps in general.
