I have the feeling that many wonders could use a buff, so there is more motivation to build them. Some seem good, some ok - but for some of them there is really no reason to build them, giving the high cost of production and a possibly otherwise good tile.
The worst for me is the Mahabodhi Temple. Sure, two Apostles are nice to have. But having your holy site next to forests may mean you have not much mountains/hills available. And another point against it is that you are basically exchanging production (rare) into faith (not so rare) since you are 'building' two apostles. The extra faith is nice, but not enough imho. This one needs a buff.
And I feel the Terracotta Army can be a bit difficult, too. I usually have no encampments in my core cities, so I have to build it at some more satellite-ish cities. I know, that's just my play stile and not the devs fault. But then the bonus of the Terracotta Army seems not good enough. I haven't played around with how good the boost to archeologists is in the late game if you are ahead of the civics tree. It may be huge in that case.
