How do you propose they do that? It's a persistent world and not every one has cleansed Orr or defeated Zhaitan but have made their way into Orr. I do like your idea that Orr would be changing but I don't see that happening without adding a whole new zone after Cursed Shore showing less Risen and more life.
Zones are 'instanced', so they could make 2 versions of Orr, the old and the cleansed. When you enter Orr you get message asking you which version you want to enter (similar to message when entering story or explorable dungeon). Just a quick idea.
The question is: when are we going to get horizontal progression?
The only thing we have is ascended - which is vertical - progression. The rest is obtainable within a very short time.
As you posted above I hope UW, DoA etc. make a return. It could be an opportunity to add some legendary armors. With scavenger hunt on the way, weapons are pretty much covered for horizontal progression. Also there are some nice mystic forge weapon skins that are not easy to get.
We lack armor, and currently top armor you can currently get is T3 cultural, which is obtained rather quickly. They need to bring legendary armor (ascended stats) and then add some rare mystic forge armor pieces (just like some rare mystic forge weapons)
That said, there should not be any more gear tiers after ascended.
