In most games I don't build Wall Street. I have a few games where I combine Oxford+WS. Those are mainly rushbuy games with the bottom line civics. Then I'll need gold once I reach the desired tech and oxford-city will often be the best place. At the same time I usually have enough other cottage-cities so I don't have to build banks just to unlock WS.
Binary research really doesn't affect anything here.
Is it reasonable to suggest that even though it may not be optimal, sometimes it's best to put both of them there anyway? Maybe when you can build it there more quickly, you have merchants or priests to settle, etc...? Also, can you still set up a corp HQ in that city?Sure, a Bureaucracy capital with both those buildings is "nice" by all means but in the big picture, it's not an optimal strategy by any means.
a) It's also likely that your capital will have the Great Library and followed by that, the National Epic. This synergizes perfectly with Oxford.
It's rare, but I just played a game and put Wall Street and Oxford in my cottage capital. I had built the Great Lighthouse, and my first GP was a Merchant, so I just settled it in place.
I was on an island, and didn't found a religion, so I wound up just plopping a bunch of settled Merchants in the capital to generate gold. The extra food from the merchants made it an even better Oxford capital than it would have otherwise been.
Other times, a settled Priest approach will put you in the same situation where it makes sense to put both of them in your capital. Whenever I built that wonder that gives you three priest slots, I tend to use them (I don't recall which one it is), and if there's no shrine to build or religion to bulb, I prefer to settle them over saving for a GA. Settled Priests are awesome imo.
