Okay, our Deus Ex Machina for PoF was the sword, we technicaly had all along. Sohothin.
Here is the problem: "How or why did it work?"
Rytlock was wielding the sword for years now (and we still don't know where he got it, btw. ) and never displayed that kind of power. Furthermore there was no indication that we were the one special person that can unleash it's full potential.
As a Mesmer I was able to conjour up multiple clones instantly for shatter and rain down fire from above. Without any explanation.
So what stopps us from doing it again in the future? I kinda believe they missed something along the line. Something like a temporary unlock or something.
I mean, all we got was Rytlock saying that he had the key all this time and suddenly, without any indication we are the God of War ourself. It kinda comes out of left field.
Furthermore, the swords are said to release their power if they are together. They are powerful magical artifacts createdin Orr and given to the Ascalonians. However we don't know where they came from. They are older than the Exodus of the Gods, but I doubt they were wielded there.
So how come we have god killer weapons with us? Sure Balthazar wasn't at his high point, but still very powerful.
Overall I believe this part does need some explaination. I would have liked if the sudden powerspike was an unlock by litteral divine intervention. A parting gift from Kormir, to show us a future power if we finally get the two swords together, or so. Like one of her handmaiden (or all of them) coming down and help us. I mean, with their wings they can go as Valkyries and I bet they could be great "angels" as they were surely paragons.
I dunno. Maybe I am just annoyed by the closing of one question by opening several others again.
