I find domination a lot harder in BTS than it was in Vanilla. That Aposaltic Palace is a big reason why. You can be full tilt ahead on war, plenty of money and happiness to keep going and the peace whistle will blow for a motion they passed. You can also have that happen if another AI is at war with the same one you are and they cause that AI to capitulate before you are done taking over territory. Then to finish the job, you have to take on them and someone (usually pretty strong) else. That Statue of Zeus can be a real headache too, you start fighting someone with it, and there's no time it seems without unhappy faces. I liked in Vanilla where you could just take people out based on geography. Another factor is this whole colonial maintenence biz they added in, you try to control more than about 6 cities on another continent, you better be prepared to either have a lot of merchants /towns building wealth or your science slider dropped down to 20% just to keep your economy up.
Generally, State Property is the civic to combat overseas empires you absorb.
