Endwalker was a great mess(SPOILERS)

[Floortank]

I am a bit curious about (edit) three things:

1. Now we have a moonship.... I guess we can start colonizing those other worlds?
2. We used the giant crystal for fuel.... is that a problem?
3. Will we have a job based on dynamis?

My guess on the first two is no, but the third, maybe?
