Replay Reward Changes?

For anyone who's replaying, do the rewards change at any point, and how?

I doubt you get 20 AP each time from a quest chain that can be completed in under 2 hours, but I haven't replayed it yet.

I was thinking the same thing. If nobody responds within the next two hours, I'll go find out.

Replaying only nets you the Saga EP1 Box.

What about exp rewards, and rewards from the shadow missions?

I think they stay the same.
