In the view of all this, I still feel the Ascians are just blinded by their memories about their own culture but do not take notice of the issues they also had as well since they see their life as the perfect life.

Amaurot society was the largest society in the world that spanned to most of the planet but as we know there may have been other societies as well and they may have a different view about the Amaurot society.

There is also the mysterious "sound" they heard before the Final Days happened. We still do not know the source of that sound but I suspect it will be revealed in 6.0 or at the Finale of this long Ascian/Zodiark Versus Warrior of Light/Hydealyn storyline (aka Season 1) in 6.3 to make way for Season 2 storyline now that Ascians may no longer exists except for memories they once did.
