Back to the topic at hand though - Y'shtola, to my knowledge, is the only Scion to have actually used Teleport in the story. Given the in-game explanation of us adventurers having significantly more anima than the general populace, and the, uh, recent occurrences in the story, I think it's safe to conclude that our characters were too distraught/distracted to focus on the process involved in teleportation, whereas the rest were unable to due to a lack of anima. Also what Viridiana said about tracking recently used "streams" of aether - that could easily start a war if Ul'dah wanted to.
