What is good about Eureka?

[KageTokage]

It looks nice and some of the NMs are fun to fight, but visuals and boss fights have always been strong points in XIV to me.

None of the things that make it unique compared to other forms of content are very interesting to me, and most of them are tedious and/or annoying (Monsters having insanely long leashes and dealing ridiculous amounts of damage if even one level higher just make it annoying to navigate the zones and discourage soloing and exploration). As some others have put it, it's basically everything people hated about old school MMOs with none of the stuff people liked.
