Actually, I almost teared up a bit to see the Rikti Invasion as the last event -- it's a crucial storyline event for both our main characters.
Although I'd hate, HATE to think of them falling in a final battle. I'd much rather the Rikti vanish forever into the sunset, and the world be saved. Now, the massive, horrible, follow you everywhere invasion -- I could do that. The better half wrote two story arcs in the AE on what the first Rikti War was like from the perspective of a supergroup of the time, and I'd love to see something like that for real -- just with a happier ending.
But that's me. I do love my HEAs.
