This update unfortunatelly is not correct about the devs statement on the patch notes:
“Fixed some issues with the AI focusing too much on Age Up that were introduced as part of the difficulty re-balancing.”
I tried multiple games after the update and from easy to hard difficulties the AI will only attack you with 5-10 units every 3-4 minutes from age 2 (6-7 minutes more or less). But then on age 4 they get lost and will send you only 20-30 units every 5-10 minutes.
The hardest AI onwards did change slightly, they will just rush age 4 in 15-20 minutes as they did before the patch. The only thing that changed is that now the armies they created will start to attack you after 30 minutes (before on patch 10 they never attacked ), however nothing on age 2 and age 3, like before. I’m so done with this game, as all of my friends, once it used to be emgaging on higher difficulties, now you can just use the same strategy over and over and win. Just give us season 6 AI where they actally attacked since age 2 on all difficulties
