I agree with this, the Shroud especially as that's always what comes to my mind when people mention HW onward zones "lacking life". The point absolutely has merit but I chalk it up to designing world zones around flying vs walking/riding in ARR and try not to let it bug me too much.
To be completely honest, I would be quite happy if we never got flying and all the zones were small, but dense with assets, like ARR. Having larger areas without loading zones between them is nice, for sure, but I got so used to them in ARR that they don't really bother me and in a strange way feel like home.
Restaurants are a perfect example. If I get something that's undercooked or a side that wasn't what I ordered, it's a simple thing to call the waiter over and say "Excuse me, I asked for X but got Y, may I please have X?" or "This is a bit undercooked, on the rare side of medium rare, would you please ask the kitchen to cook it a bit more? Thank you.". Servers and chefs don't always get everything right, all you have to do is bring up the issue politely and quietly and they'll take care of it.
The same thing applies here. "I'm not a fan of X and would prefer if it were more ABCDEF." That says what you're not fully satisfied with and gives a solution. While it may not be practical to fix, at least the solutions mentioned open up an avenue for discussion and perhaps change in the future.
