Riastrad... for one the echo visions we recieved in 1.0 happened 10 years in the past. Do you have the Encyclopedia Eorzea? If you do look at the timeline on page 53. Minfillia's (nee Ascillia) father was killed by the Gobbue in 1562. The events of 1.0 took place in 1572. And as Enkidoh has said it most of it happened via the echo and did not affect the past at all.
Edit: why is this cutscene always brought up by people to try to prove we are traveling to the past and effecting? Affecting? It in some way or another?
