Comments are appreciated. It was thought that the Elder's house was around when you only had small cities and that it was of greater use to the cities on the outskirts. With tribal council, up to three units stationed in the city have an effect on happiness, there's also the possibility of one or more resources and some happiness improvements. The thinking was that the Elder's house, if built after these, would bestow a positive effect without the -1 happy being an issue. It's just an idea; sorry if it didn't work for you.
I can't really comment on the traits. I can't possibly do anything to alter the traits themselves, though I did slow down workers following the advice of the beta testers.
I'm not sure about the duration of the wonders being too short. It depends whether or not you have a strategy to "go" for the wonders or not. For example, you can discover archery as your fifth tech and build Milon of Kroton, which, in a shield-rich city doesn't take that long. That way you can have skirmishers being churned out whilst you research everything else in the first era.
The luxury buildings are going to be more useful when there are scenarios with specific maps designed for them. Don't forget that one main aim of the mod was to be an art-rich resource for ancient scenarios. That said, I think I do need to look at resources in general.
@Saint_Gold : who am I to say you can't add units to your copy of the mod

? I'm glad you're enjoying it

Five days in and there's approx 1,200 downloads of the mod and 167 posts. I'm really thrilled by the response, which has been very positive
