I thought it was but in the end.. not really...
SPOILER MSQ
The Thavnair parts really made it feel like we were about to see some proper destruction but in the end, it did not impact much and you didn't feel any danger outside of that region.
And MSQ continued with sacrifices that are not really sacrifices since you end up not really losing anyone from the main cast.
Pretty impressive that we manage to beat Zodiark, Hydaelyn, Zenos, go to the moon and to the outer space to fight the post powerful creature and lost no one along the way.
