Players that I’ve met have a different idea:
The idea of Elite AI is gone in 1.5, however, we think it still applies. Elite AI in 1.5 are usually not ministers and control unclaimed countries that are playable. These AI are generally “smarter” since 1. They get access to elite units 2. They have more rss at their disposal 3. They have advanced code which allows them to produce more useful units and over stack. In comparison, regular AI (Ministers and one~two city countries) (Before this update) usually are more novice and produce flying bombs, build prop offices, etc. This is probably changed in this update which makes regular ai better.
