Oh yes I really enjoy playing Zhou right now. A versatile Legaty Trait, which like you said, synergizes well with the unit.
Still trying to figure out how the nomadic traits work. I've unlocked one and...it doesn't show up in the empire screen?
If you mean playing Huns and Mongols, they can't attach or build a city on their outposts. It's specified in the tooltip of their emblematic quarter which is an outpost.
And their Emblematic Unit have the Nomad trait, really unique, and strong.
Watching streams now.
Am I only one who think that Ancient legacy traits changed in a bad way? They became plain and boring. No more Harappan river industry, no experience boost for Mycs, no Nubian industry on strategic deposits, no cheap wanders for Egypt etc. I can only assume that is for balance reasons? Because so many potential tactics just vanished...
I mean, they said from the beginning than all the things like Legaty Trait maybe gonna change, because work in progress. It's why it was not revealed yet. Most of LTs were shared on discord, because we eagerly asked to have an idea how it could work, but I think we need to accept than all can change until the release, for a lot of reasons : balance for exemple.
To answer to your question, I don't think than all these traits changed in a bad way. Some looks way better to me, other ones lost in singularity.
the Assyrians one, for exemple, really fun on paper, I like a lot the idea of the free siege engines, but sadly it looked really situational and almost useless (because work only for late ancient to medieval era). The new trait is versatile, it help them to be expansionist.
At the end, most of these traits are stats. Some of the "lost" concepts, could happen later, for new cultures (?) in a new form.
