1.0 players will probably recognize this title (and no this has nothing to do with the 'Power of the Echo Buff' you get in solo story battles if you fail and repeat).
In 1.0, during certain story quests (and even class quests), there were often times when the player was asked this during the quest, and had to accept it to continue - doing so would naturally trigger the Echo and send the character into
a (usually interactive) flashback scene in the past, allowing the player to gain perspective on past events or clues to current situations.
Don't get me wrong - I love how the Echo is rendered as grainy VHS video footage in ARR, but I feel it also lost something by the removal of this player interaction, especially when it allowed the player to interact with NPCs in the actual scene in 1.0.
It would be great if this is one day brought back for ARR as I think it was something that 1.0 did great that didn't really need to be changed.
