The Difficulty of the AI

So has anybody noticed the Ai in skirmishes being alot easier to defeat? i mean i only play against hard or hardest, but I assume people who play moderate have to have noticed that the ai are considerably weaker after the de release. The beta ai was alot more promising then what we got on release in my opinion at this point the ai should go back to cheating if they surrender after 10. Playing against the ai after the release was rather disappointing because it feels like 2 steps back one step forward.
the ai in the beta seemed to be based off pure optimization in unit gathering and attacking and now i cant even say that i see the optimization in the ai after watching some recorded games recently. I just personally want to know what going on and if there is anything else i can do to help in resolving this issue.
