I don't hate Eureka. There's some things I'd like to change or improve, but it wasn't actually that bad. Levelling was a bit boring, but once that was out of the way it was fine. It's better in its current state than it was at the start. Most FATEs can be duo'd with a tank and healer/RDM. You can't really complain that instances are only half full when you can do most of it with only two people.
