I think you're being negative. The worker counters are very good and necessary to play better. In fact, they're even present in Age of Empires 2. You can easily ignore them. In the future, the interface will be configurable and customizable.
It's perfectly normal for women to build everything. And there's very little visual clutter.
Regarding the fortresses, yes, breaking the AI is a shame. It doesn't seem intentional.
I think you should make a separate post for the signalman. But this is a test.
How can you know it'll break the game before trying it? Personally, I liked producing cavalry in the barracks, haha, and I found it got a little too close to Age of Empires. Even if it seems more realistic. I find it annoying to build a fort to produce champion units.
Visual pleasure is important to many players; personally, I don't care because I've always found 0AD beautiful.
There's plenty of criticism to be made; nothing is set in stone; everything is changeable. Be positive and constructive.
