But culture does nothing for her. Her ability is expansionist, not culture based even if the ability stems from a culture item. You can probably get just as much mileage out her ability with a single GWAM. I mean if you are pressuring with her ability you don't need to "swim" in culture. You get one warehouse up and try and win one store it in your cap, then when you want to pressure you build/buy a TS and related buildings (which is probably easier with England due to bonuses to trade routes), drop in your great works, and flip a city. I think it will be much more rare where you need/are able to do the same with 3 or 4 cities. So while culture is starting point I don't see her needing to be all that culture focused to still utilize her abilities, it is certainly a route you can take but without any other culture bonuses I don't see how Elanore is any more of a culture civ than any other generalist civ.
