I'm not an Avatar person at all, but honest to god, making our coast's Pandora land based on the ocean culture of Way of Water rather than just cloning Animal Kingdom's would be genius. Hell, with this idea that Avatar 3 is going to have fire people, they could then make a Pandora land based on that at one of the other parks around the world. Kind of emulate the idea of Avatar's own vision of Pandora, spreading/representing the different cultures and experiences across multiple parks around our globe. It gives people even more reason to travel to different parks when they know they'll be getting a wholly unique Pandora experience from one park to another rather than just another (and potentially lesser) clone.
