That question is more directed to Maclaine Diemer, and maybe You can share such moments other co-composers had while they composed their music?
And the question to all of the Team and the fellow players: What is the music piece from this Game that made you very emotional?
I was teary when I listened to Aurene's Fate (the newest track), The Prophecy (also the newest from A Star to Guide Us), the whole Blish's thematic tracks: Sorrow, Determination and Sacrifice, Tomb of Primeval Kings, Demmi's theme (Demmi is my favorite character in GW2). the music in the trailer for Daybreak, instrumental Fear not this Night, Far from Home (HoT ST) and can't forget to mention A Land Restored.
I love ALL the Ambient, also the tracks that were recorded by the live German orchestra for Season 2, that I had privilege to see and hear. (http://maclainediemer.com/video/ last 3 videos).
Sister Rabbit is so cute, btw
Seek, and you shall find.
