It seems fine to me, parts of it aren't even unlocked until next week.
World content doesn't always have to be bigger to be better. They could have giant zones that are essentially wasteful space to appeal to some of the complaints in here, only for people to complain that it's then a giant wasteland. Timeless Isle was pretty compact and Tanaan was pretty big, with a lot of wasted space IMO.
It looks different than the Maw area (which is a lot better now), it's compact and the dailies really aren't that bad. I'm not an achievement or mount type of person, nor I care too much about world content, but I can't imagine that people who fall into this category hate how Korthia turned out thus far.
My only complaint is the single daily where you have to pick up those animals in a small area that spawned today.
