I would've been infinitely more satisfied by the Sundering being either accidental or the product of some manner of deception or misunderstanding rather then it being completely intentional and fueled by logic that given what little context there is behind it felt poorly grounded to me.

Just because one race vaguely chasing perfection destroyed themselves does not mean your own will be subject to the same, and we're also just supposed to believe that a race as advanced as the Ancients who were capable of creating beings capable of wielding dynamis on a catastrophic scale were somehow wholly incapable of finding a solution to their own inability to utilize it.
