Yes it coudl be better, yes, tehre coudl be more, but i've been playing around in the new zones ..and guess what I love it.
I like travelling around and finding rares pop up, and puzzles and chests, that aren't necessarily tied to a storyline, and gives me things to do in the zone that aren't hey le'ts just drop and complete the quest..
I could psend hours pvping, but still have meaningful stuff that pops up.
And best part of it, the zones also have a storyline that this doesn't interfere with.. It is getting better blizz. Better.
It reminds me a bit off classic. Finally another feature I like about this patch is that the empty cavernous zones of uldum and Vale of Eternal blossoms actually have some meaningful activity. Great way to re-use a zone.
I say this is pretty much carrying on from Naz'jatar and Mechagon.. except that i feels a lot better in 8.3 when the zones are actually that large.
