I have a feeling #1 could be the one of the biggest additions out of them all.
1) Don't pay the ferryman
No more loading/unloading troops! Rise of Nations introduced the idea of naval transport by having your military units turn into little boats when they hit the water, and then turning back into army units when they hit the beach. No one missed having to babysit a bunch of empty transport ships that would only be used once every few centuries. Civilization V borrows the same idea by automatically giving your units a trait called "Embark" when you hit a certain tech. This lets them turn into boats whenever they need to cross water.
While its not an instant unit skill since it will require Optics to get Embarking, its not that far off from the start either. Its a nice feature in that galleys and other transport boats were annoying because of their low capacity but at the same time they were a good check militarily for both you and the AI. You couldnt just at a moments notice invade someone across the water unless you had enough boats to ferry your army across and had them in position to do so. Now with Embarking all you need is your unit there and youre all set.
With the new one unit per tile I would think Embarking wouldnt be needed since Civs will have far fewer units and thus need to create and maintain far few ferry boats to mobilize their armies. I kind of think this wasnt done because it was wholly necessary or greatly positive to the strategic aspects of war but rather to help catalyze wars themselves removing one of the major barriers for the both players and AI. I hope it just doesnt make things too easy.
