The thing is, it's not necessarily how they do the content - it's the fact that they condemned Blue Mage to it. They basically took Blue Mage, which many people, including myself, have wanted for a very long time, and relegated it to side content.
The Carnivale and the like could all be pretty fun as solo content in general, but the various actions that you'd need to succeed in it could have very well just been in a Logos-like way instead of relegating one of the most desired and potentially interesting Jobs in the game and putting it in completely irrelevant content exclusively.
And yeah, there's the "compromise" of being able to use it in Party Finder, but that compromise shouldn't have to exist to begin with.
