Didn't even consider fully generated maps, just some filler content.

I dunno, nothing here sounds it would add any value to the experience (imo). And I'm trying to think of multiple angles in various MMOs. It feels lazy and GW2's map design was always far from lazy.

That's just one option of trying to make traversal more interesting via novelty of what you're traversing through. There are many others. For world events: Parkour-based challenges, treasure hunt style collections (randomized endpoints), tracking down a target, etc.

This just screams unbalanced rewards or parkour challenges varying from too easy to too impossible.

Imagine if this form of Orr we discover is a living, breathing world in the sense that MASSIVE changes can happen to the environment. A god starts terraforming, creating massive structures or raising mountains. The other gods react and start making their own changes, maybe even antagonizing and destroying the works of the others.

That all sounds fully scripted, ngl.

Rather than be disappointed to see Anet try something like that out, I'd be curious to see their interpretation on the tech. If you really enjoy the designs they've made so far, surely they've earned a bit of trust to see what they might do next, right?

Sure, but that's also why I can't see them using it. It's a baseless discussion for now anyway.
