Another thought, that would be nice to see included in the Unending Journey is re-done cutscenes from 1.x that can be unlocked via the Echo ability. This should be available to all players, not just legacy, so that we can see the entire story from 2010 until the present.

The echo provides for so much awesome that it felt underused in 1.x, and I worry that it takes only a secondary role in A Realm Reborn. It seems important enough, as it did in 1.x, through the level 24 quest(s) but it still feels downplayed.
