Maybe we're talking past each other, so I'm sorry for misunderstanding. I agree AK needs more capacity as a whole. That's priority #1.
Going past that, if you look at the wait times I posted - the whole park is unbalanced which is why you see plans for Dinoland and the Tree of Life upgrades. You need to pull people out of Pandora and spread them around the park. Hopefully the new stuff does that. That's why Dinosaur is being underutilized.
As to bring more people to the park, the park empties out the later in the day you go. If you can either A) keep people in the park longer and not hop to Magic Kingdom or potentially give me people a hopping target helps other parks.
