The way Square Enix depicts our characters...are we helpless, or are we heroes?

[Elexia]

But what if your not a rank 70 Dragoon but a rank 70 weaver?

Then you shouldn't be allowed to take part in the storyline? o.O

Seriously though, that's actually one of the reasons they're portraying us as adventurers rather than heroes, because not everyone is a combat specialist, and this isn't our story to quote FFX, it's more we're actually wrapped up into something already preexisting and they're building us up. The engine is the reason FFXIII was as it was, so XIV can likely do the same thing but XIII's storyline was a constant fight for survival, nothing of that nature has happened in XIV yet but it looks to be approaching.
