I do have quite a bit of fun in Abyssea region. Well, I cannot go Atma "God mode", so sometimes I got my butts handed down quite well. For the few Atmas that I do have (some Japanese friends bailed me out with Atmas...), it does let me do things that I cannot do in the past (like having summons out full time, and you can make them regen HP!).
I do think some of the NMs in Abyssea can be quite hard without the Atma buffs, so I bet the NMs inside were quite hard at one time.
As for Voidwatcher, I have not even tried them before. Nor I have even been in Walks of Echoes as well. There are quite a few "older" contents I have not finished as well (missions and new summons).

Art for the sake of art itself is an idle sentence.
Art for the sake of truth, for the sake of what is
beautiful and good — that is the creed I seek.
- George Sand
A designer knows he has achieved perfection,
not when there is nothing left to add,
but when there is nothing left to take away.
- Antoine de Saint-Exupéry
