Apparently, from the pre-release version given to streamers, the AI seems to not have been improved (that much). Marbozir has made a video about that : In particular, if you go at 1:05 : "... litteraly never use any air units at all, I have yet to see the AIs use them." If it's confirmed for release it will be a huge disappointment for me, to the point I think I will not buy this expansion (pre-purchase cancelled due to that). It's not normal that two years after release (and twos expansions) the IA is still not functional and able to use all the features of the game. I do not speak about being good, I just speak about being functional and use the features of the game.
