FF is not GoT.

Terrified is better than bored.

In fact,one of the reasons Heavensward has been a lot better than the plot in ARR, is because this is also affecting (on a subtler level) the main character. The choices in dialogue and ultimate path the story takes is still vague enough to fit any type of character in, but it goes to show that no one goes through such personal hardships unscathed.

This also sets the stage for further character growth, where before there couldn't be any. To simply fight to gain the power of being a hero, well we already are a hero now, damn important one too. But to just stay that way, and just throw in "find the crystals again" bit through expansions, makes for a boring and rote character. That's because we already know they are strong and supported with or without the blessing.
It is one thing to become strong, to get The Blessing back, we were almost kinda of expecting it over and over. but what if next expansion we had to work though our inner demons? Or give The Blessing to others? Or maybe find that reason to believe in Eorzea again? This is what keeps things fresh in the story, to make a character that lives and feels within the setting, not apart from it.
