- Accuracy? Great Wall is just a famous specific wall at the north China. Being a building of the scenario editor would be better than an unique tech in my opinion. But this is not the main cause of the problem.
- Don’t think so one-sided please. You can see that every Britons game researches Yeomen but Chinese game is not. Chinese has great defense already and improving the defense abilities is totally not urgent than improving the archers’ range, so people may not be attracted by Great Wall like Yeomen, this is why I said the comparison is unfair.
- I explain again and again that I never deny the benefit. However the low attraction is still a problem when it is an unique tech, especially it costs stone, a super precious resource in the late game, the time you finally need the better defense indeed. This is the main cause of the problem. Maybe you don’t consider it is not attractive, but the reason I just stated before. Chinese not goes BBT rush as often as other civ like Teutons, that is also one of the reasons.
In the forum in my country, Great Wall is the tops of the list of the meaningless unique tech. Buffing is not the point. There definitely is a solution to deal the low attraction and keep the balance for it.
