The world is definitely smaller and more cramped than it was in 1.0.
Yes, the copy-paste terrain was pretty annoying at times, but at least the world felt like a world and not some tiny area you can run from one end to another in a minute and watch the zone loading screen just to do that again. Unless you want to teleport. Teleport locations are also close to everything, so you really don't have to worry about traveling at all. Especially now that there's no concern that anima would run out.
There is no place for enjoyable map sequences like the Moogle pre-req quest from 1.23 or something. You had this labyrinth in Shrouds where you had to move under the aggroing Guardian Trees. Your party would have to walk past them or they one-shot anyone running. The maze-ish forest had you kill five NM's to gain access for Moogle battle. The area in which the Guardian Trees were, was probably bigger than some maps in 2.0 in itself, and it was just a tiny portion of Black Shroud.
The copypaste terrain didn't bother me because behind all the copypaste was a different and unique location. You had Ifrit's cave in Thanalan high in the serpentine arcs of stone connecting the mountain sides. Ifrit's cave in itself was a comfortable place to chat and craft in between the primal battles.
Garuda's lair was hidden in Coerthas behind ghouly tunnels and in the far back behind a multitude of aggroable mobs which you really wanted to avoid or you'd have to spend time killing them (which was not a simple spamfest)
The areas barely touched by players (mostly in Coerthas far, far in the north-west) had an immense feeling of loneliness in them. Boars roamed the coves between mountains. Abandoned vigils stood on the hills, facing the never-ending loneliness and completed by the amazing, hauntingly beautiful soundtrack. Did they need to be there? maybe not. Did they succeed on adding the right atmosphere? hell yes. And maybe there would've been some use to them in later content.
How about the job quests that had you travel to far away places and watch some actually interesting story-telling? You felt you were far from your home city, now the states feel like they're simply behind the corner, all the time.
There is no danger nor joy in riding your chocobo through the land of 2.0, every zoning breaking the immersion SE so dearly tries to protect.
So if the map was bigger they would need to copypaste more again. Give me a break and take a look at the map of Guild Wars 2. SE is just lazy.
