I'm with @wowgetoffyourcellphone on this one. I find the current tooltips show way too much information. Along time ago I even locally made some mockups revamping them, but I'm afraid those have been lost to time. In fact, I thought about using bars to visualize numbers like attack damage and resource gathering speed, which is still an idea I like.
It would be cool to work on this, but for me it's a matter of time, I have so many things I'd love to implement, but they take time and I can't work on too many things at once. I genuinely hope, though, that I'll get to it eventually and I'd also be happy to review PRs for it. @wowgetoffyourcellphone, same for your viewer mockup. https://gitea.wildfiregames.com/0ad/0ad/issues/6860
(I personally prefer icons, by the way, and it would also be nice to add an option to choose between reduced vs extended tooltips)
And, I forgot to say, doesn't give unfair advantages, quite the contrary, unfair would be to force a group of people use an UI scheme that makes things harder for them.
Also, if some people prefer text and others icons, it would be great if both are menu options. This way @wowgetoffyourcellphone's improvements can stay under the text option, and if some day someone wants to do the icon variant, then that's added under the icons option, nothing is wasted and everyone is happy, I guess.
You can blame me
This is actually not a mistake, it was a deliberare decision, which I was involved in. See the discussion in https://gitea.wildfiregames.com/0ad/0ad/pulls/8062
The idea was to make the civilians' names more interesting, to change them up a bit for some civs and add historical flavor; most of the lower-class civilians in the Han dynasty were indeed farmers, and after all, the unit is best at working on fields.
I was aware at the time already that this idea was not without its flaws and that someone would bring it up eventually. But I still stand by the decision, I think it's a good opportunity to reflect and teach what kind of people actually formed the lower societal class in those civilisations; and for me personally, that outweighs the oddities.
And if you really need one to pick on, then please the "Carthaginian Artisan"...
